JMBSG,
Can you see all the pictures of the example guns? Lloyd was having problems.

You're welcome. I agree, the Winchesters (12s and 97s) do have a fine finish, inside and out. But I just love the Stevens take-down and that it's milled out of a block of drop forged steel. They just feel more substantial.

Glad to see this topic.
I have a Stevens Model 520, although mine is a Montgomery Ward's Western Field Model 35. I love mine, love shooting it, but at this moment the action arm is at the Gunsmith being welded as it developed a stress crack sometime over the last eight decades... Can't wait to get it back!!!
Anyway, I was amazed to find that mine was a lot "newer" than I thought. I had thought mine to be of late 1920's or early 1930's vintage, looks like mine is late 1930's vintage, not that it really matters in the grand scheme. Mine has the "cross bolt" safety.

Glad to see the Stevens Model 520 get some attention. I just hope that the prices don't go totally outer limits before I can afford another or more...
Thanks
Mark

Outstanding thread! I cannot see the additional pics either.

No, I just see a title and the word "image" beneath the added graphics. Right clicking on the word "image" and then copying image location, I get such as the following:

https://lh3.googleusercontent.com/KNv1- ... 11-h731-no

Entering that on my browser destination line yields a Google log in page. So it seems that perhaps your added images may be locked in a personal account and not available for public viewing. Just a guess, I'm not a computer nerd.

We're thinking on the same lines. I figured it had to be a permissions problem so I moved everything to an album on SGW. Any luck?

Jim: That fixed it. Everything I hoped it would be. You know, I've paid good money for books on guns that weren't this useful. You've really provided a first class reference for folks here. The unintended consequence of all this might be a mild run on these guns (now that you can figure out what you're actually getting). Stock up while you can!

I did not even know there was a problem with some photos not showing up... There was even information getting through that I was soaking up that I did not even notice. Was glad to see more photos when I did check this out again.

Jim: Went back and carefully re-read your original post (with all the additional photography). Lots of information to digest here(!). Both of the Western Field Model 30s I own have the later (#74) type of ejector, but the 12-gauge doesn't have the front breech-block screw on the left-side of the receiver (the 20 does). Go figure?

I also carefully looked over the early 520 advertisements that Dr. Drew provided. The model numbers and prices are interesting. Beginning at the field-grade, plain barrel 520 for $25 and ending at the Model 535 for $100 (w/522, 525, & 530 in between). Sadly, I have only seen photographic examples of the Model 522s (the Trap Model) and the 535s. It appears to me that the post-1925 Model 30 numbering sequence (for all makes, including the Riverside versions) is Model 30 for the plain barrel field-grade guns, Model 31 for solid-rib versions and Model 35 for the post-1938 non-suicide safety guns. Are there model numbers that I'm not aware of? I'm now assuming that sub-gauge guns used the same numbering sequences?

From what little advertising I've seen for the 620s, they used a similar system (620, 622, etc.). Last questions: What safety did the early 620s use? Inside of the trigger guard like the 520s? Also, what are the differences between the 620s and the 620a guns?

lloyd,

It looks like you have one of the guns, w/o the breech block stop screw, I mentioned above in my second reply. One just sold on GB (Ranger 33-37 Early type w/ 32" barrel), didn't get my bid in time. I'm thinking that's a one or two year model in the middle of the 33-37 range. Like they tried something out, didn't like it and changed it back. Does it have any sort of internal device to stop the breech block from sliding out other than the pressure from the cartridge stop?

The Stevens advertised model names are in the following catalogs:
1909-14--520 (base), 522 (trap), 525(?), 530(?), 535(delux) (Stevens reuses the 530 name later double barrel shotguns)
1920-25--520 (base), 522 (trap)
1928 Wholesale--620, 621 (both field grade take-down)
1928 #57--520 (Riverside), 620 (field grade), 622 (trap)
1929-38--620, 621 and 620 Riot (1935-37)
1939-40--620, 621, 620P (poly-choke)
1946--620, 620P (poly), 620CS (skeet)
1947--620, 620C (skeet), 620 Aerodyne (?)
1948-51--620 only
1952--620, 620C, 620P, 620PV (?)
1953-54--620 only

Sears sells them as Stevens 520s until 1924 and they offer the 620 one year in 1927. At all other times they market them under the Ranger/Ranger Repeater name and never mention model designations, however they are sometimes, inconsistently, marked on the guns:
Model 30 (520)
Ranger 30 (520A)
JC Higgins 102.25 (520A)

Montgomery Wards sells the guns under the Western Field name with the additions of "Deluxe" and "Browning" on some guns. It gets confusing here because they use 17 different model numbers.
Model 30 (520)
Model 35 (520 w/poly-choke, these are 1938-39 guns and I can't confirm if it's only poly-choke equipped guns, I've seen them w/ and w/o but they may have been cut off)
Model SB30A (520A)
Model SB33, SB033 (520A w/poly-choke)
Model 060 (620)
Model 60 (620 Deluxe and 620A)
Model 60SB (620A)
Model SB620A (620A)
Model SB60A (620A Deluxe)
Model 61, SB61A (621 Deluxe)
Model SB66, SB066 (621 Deluxe w/poly-choke)
Model SB067 (621 Deluxe w/comp)

It's more confusing than Japanese car nomenclature.

All the 620 family of guns had a cross-bolt safety behind the triggerCORRECTON: Early 620s had a trigger safety, see picture below.
Image
Stevens Insert to Catalog #57 Revised (1929) this is the introduction of the 620 20 Ga, notice the cross bolt safety behind the trigger.
The differences in a 620 and a 620A are:
620s have a receiver tang and a trigger tang (the stock is held on with a screw between them like the 520s) and they use a flat main spring.
620As do not have tangs (the stock is attached w/ a long draw bolt through the butt stock) and they use coil main springs.

As far as I can tell the gauge, barrel length have nothing to do with model designation.

No, the earlier 620 shotguns had the "suicide safety" inside the trigger guard. This is shown in the add pic you posted, repeated below:

I have seen these from time to time on GB, but they are fairly rare as compared to their cross-bolt successors. In any event, thanks again for posting this illuminating info, happy to see your additional pics made an appearance.

Good Catch, I stand corrected by my own evidence! I've never seen one of the 620s w/a trigger safety so I didn't even think to take a closer look at that ad. The 620 identification guide is the next project so hopefully I can tack down when this change occurs.

Thanks

Jim, this is the gun I have without the breechblock screw on the left side.

Image

It's a 28-inch modified choke gun I picked up as a project a few months ago. As to your question about how the breechblock stays in the gun....I'm not sure. It doesn't seem to be an issue when it's dissembled.

I see the ejector location isn't the one I thought it was. The 20 variant I have is in the forward location, so I assume this one is an earlier gun.

Yup, definitely a gun from the early period of 1933-37 based on the ejector position. I'm guessing that you just push in the cartridge stop in order to pull the breech block/carriage out. Having the stop screw seems like an unnecessary extra precaution once the spring steel cartridge stop was introduced after 1932. With the earlier rocker style cartridge stop the carriage can push it out of the way and fall out, especially when the parts are worn. I guess that Stevens found out it needed that extra level of safety for some reason and added it back to the design, maybe once parts started to wear. I have a 1920-24 gun where the breech block falls out even when the stop screw is fully in, not planning on shooting that one any time soon.

As a side note, here is a picture of what the breech block stop looks like on pre-1915 guns, it attaches from inside the receiver.

Updated with more 520 family Stevens catalog pictures and a picture of a 1929 620 20ga w/ a cross bolt safety. Great thanks to Researcher01 for the Stevens catalog support.

This topic just keeps getting better!! Even better yet, I dropped by the Gunsmith yesterday and my action arm was done being re-welded! My Stevens 520/Western Field Model 35 is back, complete and working!

Not to hijack this thread, but maybe a small diversion. 8) I've been accumulating fore end pieces so as to be able to replace a 620 hunting barrel with a short HD barrel without disassembling the whole thing. I just got an action arm and fore end barrel and noticed a problem. There's a straight saw cut across the fore end barrel to help anchor the riveted arm, leaving sharp angles at the ends of the cut. Of course, to a metallurgist this smacks of fatigue failure, and, sure enough, there are cracks at both ends of the saw cut. One is pictured below:

Image

So are there any informed recommendations to halt these cracks and preclude further ones, either drill them out or hit them quick with a welding arc and then round out the ends of the cut?

JMB,
I have not had one crack that I know of. But I don't usually dismantle the slide assembly, maybe I should take a closer look. I don't see why you couldn't weld it up. Here's one, w/ wood, for a great price on GB ($39)

JMB,
You say you're building an HD 620 barrel set. This parts block for a WWII US Mil issue 620 had all that you need but it got crazy at the end ($282).
