This guide is for the Browning A5 16 gauge only. Browning 12ga numbers began with the number 1 in 1903. The 16ga number 1 began in 1909. The two sets of numbers are different. A common mistake I have seen in many, many, gun shops and online sites is to assign the 12ga serial number date to a 16ga.

I compiled this quick reference serial number guide for dating 16ga Browning A5s and the Auto 5-3 Shot, by serial number. I decided to share it here since this is where much of my limited knowledge came from.

The serial number and dates are approximations only. These dates were gleaned primarily from Sauerfan's timeline and the Shirley/Vanderlinden book. Details about dates, transitions, exceptions, and other nuances can be found in the Shirley/Vanderlinden book, Browning Auto 5 Shotguns.

I took the liberty to use the Calendar Year Jan. 1 - Dec. 31 for the X series. FN used the Fiscal Year July-June. Other factors need to be taken into consideration to properly date your gun. I found what I thought was a very early 1948, Sweet Sixteen, based on the serial number. Browning informed me the gun left the factory in 1955.

1909
1 - 3200

1910 to 1914 There is only vague info about 16 ga SNs in SV (page 74) for the time 1910 to 1914. SN's 3201 - 15000 were invoiced between 1st Jan. 1910 and 30th June 1913. The last shipped before the outbreak of WWI was SN 19642.

1915 to 1918 No production due to German occupation of Belgium during WWI.

1919: 19671- 20500
1920: 20501 - 22237

"are so out of sequence there is no way to establish accurate production dates" S/V p76
1944: 126201
1948: 131738

1947 Post-war Belgium made "X Prefix Series." No serial number distinction between the Sweet 16 and the Standard 16 gauge A5. This is the "unmarked" Browning, era of the Sweet Sixteen.

These are among the rarest of the A5 Sweet Sixteen but are priced as standard 16 gauge A5s in value guides. This is the first year of standard production of the 2 ¾ inch chambered 16 gauge. It is also the last year of the non-engraved sweet sixteen. The popularity and success of the Sweet Sixteen from 1937 through 1947 earned it a permanent place in Browning marketing as the 1948 engraved "Sweet Sixteen." 1947 is also the only year the 3-shot 2 ¾ 16ga was marketed in the USA. Getting one of these extremely rare original factory-issued guns at a standard gun price is a trophy in itself.

1947 - 1953 "X Prefix Series"

1948: X13667 - X23501

1951: X43701 - X59400
1952: X59401 - X77700
1953: X77701 - X99999

1948
Introduction of the "Sweet Sixteen" in script engraved on the receiver. Prior to 1948, no sweet 16 was factory engraved "Sweet Sixteen." Glen Jensen, Browning Historian took the position with me that the true "Sweet Sixteen" was born when the receiver was engraved "Sweet Sixteen" in 1948. He acknowledged the lightweight A5 16 gauge guns produced between 1936 and 1947 are in fact Sweet Sixteen and identified as such in the factory-issued catalogs. If the serial number records archived at Browning indicate the non-engraved guns are a Sweet Sixteen, Glen Jensen would issue a letter on Browning letterhead with an official seal for a fee authenticating the gun as a "Sweet Sixteen." Since Glen Jensen's retirement in 2014, the Browning Customer Service department continues to provide research on individual guns and if records exist will issue a letter documenting requested information.

1953 - 1954 A - Series "A" in front of or above the serial number. These guns were a transitional series between the X and the below R/S marked guns.
A1-A958

1953 - 1957 R = Standard Weight, S = Sweet Sixteen

R 74701 - R 99999

1954-1974 The "Y" Series, Also known as the Why Series. There seems to be no functional difference or reason for this series. According to S/V p.77, 4,773 Y Series guns were produced. Only two are known to have been shipped to the U.S. There is no serial number distinction between the Sweet Sixteen and Regular Y series 16ga. As for dating this gun, the date code on the barrel may be the most reliable source. An example and discussion of a Sweet Y gun are featured on p.34-35 of this guide.

1957 - 1958 Second series of "A" prefix
A Serial Number 01 November 14, 1957, and T Serial Number T229 November 24, 1957
1957-1958 A or T #01 - 10900 A Indicated Sweet Sixteen and T indicated standard 16

1958 - 1967 The single digit precedes the S and R. 8S,8R = 1958, 9S, = 1959, 0S = 1960, 7S =1967

1958-1977 FN High Grade Lightweight Series May include the letters following the serial number "SAC,B,F,N,Z" S/V p81
***1958 #001-17595 These will have a small two-digit (year 59 = 1959) number following the serial number. Some have shown up with the entire year stamped instead of the two-digit year code.

***1966 - 1977
***17595 - 26022

1964 was the last year of the "R" (4R) Standard Weight A5 16ga.

1968 - 1976 The two digit year precedes the S. 68S = 1968, 76S = 1976

1976 Japanese Production Began, however, FN still produced Browning "Made in Belgium" shotguns into 1984, SV p65. The serial number coding system changed to the serial number preceding the date code. Serial began with 1000 - 99999 followed by the model code 221 Sweet Sixteen and 171 Superlight 16 and two letter year( T=6, R=7, P=8). see Browning Website

1976
1000 221 RT - Sweet Sixteen
1000 171 RT - Superlight Sixteen
1978
1000 221 RP - Sweet Sixteen
1987

Wow. Just bought a 1926 Browning A-5 16 ga today, serial number 421XX. The owner said the barrel was modified by a Browning to add a ring between the barrel and receiver so that it shoots 2 3/4 ammo. It also has a choke "thingy" and a new pressure plug? that is set for low-base ammo. It was set up for his grandson, who outgrew the gun and went into Rem 1100 12 ga. I owned two Sweet 16's when I was in my late 20's - early 30's, but I don't remember anything about the pressure plug adjustments.

So, if I have a 16 gauge and the serial number starts with X561, that is a 1951, correct? I am sorry to ask a silly question. I am not familiar with this gun or any antique shotguns. My husband inherited it from his grandfather and we are trying to find out more about it (not to sell it, for personal knowledge).

Hi, Welcome to SGW. Dating these old guns are at best an educated guess. The dates listed here are based on records/logs with the range of dates. I found three different lists but these dates seem to be the best. My experience has been that you are correct in guessing along with us that your gun is dated 1951. It may have in fact have been produced in 1951 but left Browning one to three years before or after 1951. It gets complicated as to why some were early or late. Thanks for the opportunity to answer a great question. Please feel free to ask other questions you may have on that gun.

My first post.

Thank you for putting together this information. Could you please explain how a gun could have left Browning one to three years before it was "produced"? I am interpreting "produced" as actually manufactured, which must not be right because then it would be an impossibility.

My father just passed away and gave me his shotgun. Its serial number is S 63661, which puts it into the year 1956. However, my father always told me that he got the shotgun as a high school graduation present, which would mean sometime around 1949 or 1950. And I am fairly certain that I have a picture of him, misplaced right now, that show him with the shotgun in the earliest 50's.

Hi Ronyahski,
Thanks for your response and question. The date discrepancies are due to three factors: 1) The FN factory stamped serial number, 2) The FN/Browning inventory date, 3) The Browning shipping/sale date.

I now own 7 collectable (to me) Browning A5s. I have called the Browning historian on each to discover all I can about each gun including when the gun left the Browning factory. No factory records could be found on three. The Browning historian informed me of the dates four of my guns were sold and shipped from Browning. I have letters on Browning letterhead on three of my guns.

Of the four guns with factory records, two had serial numbers that matched the published serial number dates listed in The Book "Browning Auto-5 Shotguns" HM Shirley, Anthony Vanderlinden. One gun left Browning one year after the published serial number date. One gun left Browning two years before the published serial number date.

The gun that left Browning a year later is easy to explain. It was manufactured in Belgium and had the serial number stamped in 1946. It was shipped to the Browning warehouse in November of 1946 and has a serial number date 1946. It was sold and shipped from Browning to a customer in 1947. The letter dates the gun as a 1947 gun. It is a contender for the earliest (lowest serial number) A5 Light Twelve made. The A5 Light Twelve was not available until 1947. This was all during the first year of production after WWII. This gun was held in the Browning warehouse until someone ordered an A5 Light Twelve. A gun configured a certain way may sit in the warehouse, weeks, months or years until that configuration was ordered. As I mentioned earlier in my post I found a 1948 serial numbered gun that left Browning in the 50s.

My other gun was custom ordered. The special custom order was sent to the Belgium FN factory by Browning 1935. There were thousands of barrels, receivers and other parts on hand and in stock at that time. In 1935 parts were made years before they became a finished gun and logged into Browning inventory. In 1935 my gun was made with the most recent available parts. These parts were stamped with a serial number that would normally have made it into the 1938 inventory as a complete gun. In 1935 the Belgium custom shop took the fresh parts and assembled the gun with the custom configuration and shipped it to Browning in the 1936 inventory. This gun was received in the USA Browning warehouse in 1936 with a 1938 serial number. The letter from Browning shows the special order configuration and date it was shipped to the customer, early 1936. This type of scenario is outlined in "The Book."

Some owners/collectors declare the serial number date. Some owners/collectors declare the Browning factory issue date. Hope this helps.

I recently received a Sweet Sixteen from an estate, and have two questions, please...

1) I cannot match/date the serial number on this shotgun. The serial number is located just forward of the loading port and is 'A427', exactly as written (i.e. the 'A' is not above the rest of the numbers). This serial number does not seem to match any of the examples.

2) The shotgun came with an attached 'Poly-Choke', the type of which I've never seen before, nor can I find any info on how it works. Does anyone have any ideas?

I have photos I can post for both questions, if that would help.

Thanks!
Jon

I suspect it may be the Remington made Browning. The links below offer more history. The three digit serial number may also indicate a 1940 gun

****1940 - 1953**** "A" Prefix American made Browning by "Remington Arms."
Thanks for the reply, but I don't think this is it... The serial number is just forward of the loading port (not on the receiver as these serial numbers are) and the number is way outside the range listed for the Remington-made shotguns. Also, my shotgun does have the FN stamp, so I'm making the assumption it is Belgian-made.

Hi Jon,
Very cool first post in the forum. Thanks for the information rich question. I revised this guide to prevent future confusion. The Belgium "A" series guns I have seen, most on GB and other online auctions, have the "A" above the serial number. The Remington/Browning A5s had the A preceding the number.

Thanks Researcher01 for referring to the book.

"Details about dates, transitions, exceptions, and other nuances can be found in the Shirley/Vanderlinden book, Browning Auto 5 Shotguns."

I now believe with certainty that your gun is a 1953 production Browning, post war, made in Belgium, Sweet Sixteen with a Polychoke. We may be able to determine if it was Browning - Choke code #11or FN - Choke code #9 factory installed choke. If you unscrew the choke you may reveal a choke code number stamped into the metal just in front of the threads. I have one (1946) with a choke code #15. I have no idea who had that code but I have seen two others with that code.

Thanks for the pictures. With your permission I would like to post the pics with the close-up of the serial number and choke code as an example for others to see.

Polychoke

Many thanks to both Researcher01 and Goad. I appreciate the further information...

Goad - yes, you have my permission to publish the photos. Also, I removed the PolyChoke and found a stamped "#18" between the threads of the choke and the front sight at about the 2 O'clock position relative to the sight. Does that help? Thanks also for pointing out the crack in the forearm - I plan on taking it to a gunsmith to have them glass it internally to prevent further cracking/damage. Any advice along those lines? Your links for the PolyChoke were spot-on, as well. Why I couldn't find that myself initially is beyond me (a forehead slapping moment to be sure). I was able to contact the manufacturer and was able to translate the settings to their modern equivalent (for those that care, here they are):
