Belgian Shotgun Identification

The Banc d’Epreuves de Liege proved 233,526 double barrel smoothbore guns in 1889, the majority for export. In 1899 alone, the U.S. firms of Hartley & Graham and Simmons Hardware bought 90,000 shotguns, rifles, and handguns from Liege gunmakers. Most of the Belgian guns imported before WWI were not of high quality when new, and NO vintage shotgun should be fired, with any load, until examined by a double gun spam smith.

Final proof is the crowned ELG mark.
The Perron (tower) indicates provisional blackpowder proof even on guns later voluntary proved with smokeless powder; which are marked with a Lion over PV. If there is no Lion over PV, the gun was NOT proved for smokeless powder.

The usual c. 1900 Belgian 12 gauge bore would be 18.4 mm = .724"
Conversion table - 1 millimeter = 0.0393700787 inches
http://www.convertunits.com/from/mm/to/inches

Date of Manufacture
NON POUR BALLE - choked unrifled bores used 1878 - 1897
1898 - 1910 – Bore in mm (22 cm from breech) and muzzle (choke constriction) appear next to each other after ‘choke’
1910 – 1924 – Bore in mm is over muzzle dimension

Prior to 1924 the gauge would be indicated within a diamond.
Post-1924 - A 12-70 in an Omega lying is the gauge and chamber length in mm., and would indicate the gun is chambered for 12ga 70mm - 2 3/4” length shells.
Please note that many Belgian guns will be chambered for:
2 1/2” - 63mm 20g,
2 9/16” - 65mm 16g,
and may be 2 5/8” 12g.

Date of Proof codes– Lettres Annales used after 1921

Another version of the Greek letters 1948-1961



Poincons Officiels du Banc D'Epreuves de Liege from "Trade & Hallmarks on Firearms in Belgium" Bruno Joos De Ter Beerst, 1998



1 millimeters = about 0.04 inches
70 mm = 2 3/4" chamber
17.0 = .670"; 16.3 = .642"; choke constriction of .028" or 16g Light Full
18.0 = .709; 18.7 = .736"; choke constriction of .027" or Improved Modified
18.4 was the usual c. 1900 Belgian 12b = .724"
After 1924 the markings were "Choke" and bore only.

Barrel weight at the time of Smokeless proof: 1 kilogram = 2.2046 pounds; 1.3555 Kg = 3 pounds.
May also be stamped '1K3555' after 1924 without the decimal.
If the barrels now weigh >3% less (from honing), the gun is considered out of proof

The Lion Rampant over PV was introduced for military rifles of 8mm & smaller in 1898 & then applied to the supplementary smokeless proof for shotguns in 1903. It was mandatory post-1924. Lion over SCH or EC were optional smokeless powder proofs used 1891-1924 for "Schultze" or "EC" powders.



1853-1877 inspector's (controller's) marks were crowned rather than spangled.

PLEASE NOTE: Inspector's marks can not be used to establish date of manufacture; they were re-used over time and the significance of some has been lost.

Load data used 1897-1903



12g Manufacture Liegeoise likely proved with Mullerite (stylized lion over M) for a service load of 2.70 grams POUDRE = 41.67 grains = 3 Dr. Eq. (42 grains). "E.C." No. 1 & "Schultze" were also 42 gr. = 3 Dr. Eq.
36 grams PLOMBE = 1 1/4 oz. shot

Hi!

I have inherited a F.Dumoulin & Cie Liege of my grandfather.
It has been a little difficult to identify which year that the shotgun is made ..
And I hope to be able to use this fine weapon to hunt grouse in the future, just like my grandfather did.
Hope you can help me!

Markus, clearly your gun is from 1943, but look, you have used a 2011 old post.
Best regards

Belgian Service & Proof Load Pressures

Banc D'Epreuves Des Armes a Feu De Liege (Proof House for Firearms of Liege) 1906
https://books.google.com/books?id=5fxGA ... g=PA52&lpg
12g - about 1 1/4 oz. / 3 1/4 Dram Eq. (1220 fps).
(12g 5.8 grams = 89.5 grains = 3 1/4 Dram)
16g - about 1 oz. / 2 1/2 Dram Eq. (1165 fps).
20g - about 7/8 oz. / 2 1/4 Dram Eq. (1155 fps).
Powder was not specified, but appears to be a Black Powder No. 4

After the proof house revisions of 1924, a Certificat d’epreuve could be issued and specified:
“The pressure developed, measured by crusher type device , lower or equal to 600 kg per square centimeter for sizes 16, 12, 10, 8 & 4; 670 pounds per square inch for sizes 20, 24 and smaller.”
600 kg/cm2 = 8534 psi SERVICE pressure;
670 kg/cm2 = 9530 psi SERVICE pressure
+ 10-14% by piezoelectric transducer measurement.
20 g was PROVED at 1000 kg/cm2 = 14,223 psi
12g PROVED at 900 kg/cm2 = 12,801 psi
Transducer numbers for 20g would be close to 15,500 psi; 12g about 14,000 psi



The Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives standards were not ratified until 1969.
http://www.cip-bobp.org/homologation/en ... _type_id=7
Pressures are measured by transducers
12g 65mm and 70mm “standard proof” lead or steel (limited to no larger than 3.25 mm and max. fps 1,300) SERVICE pressure 740 BAR = 10,733 psi; Maximum statistical individual pressure 850 BAR = 12,328 psi; PROOF 930 BAR = 13,489 psi.
Both 65 and 70 mm 16g standard is SERVICE 780 BAR or 11,313 psi; PROOF 980 BAR or 14,214 psi.
Both 65 and 70 mm 20g standard is SERVICE 830 BAR or 12,038 psi; PROOF 1040 BAR or 15,084 psi.

Lettre Annale / Date of Control marks can be difficult to decipher
Lower case cursive 'p' = 1937
Spangled B = controller's mark
Stylized lion over PV = Smokeless Proof
Crowned ELG = post-1893
12-70 in an Omega lying = post 1924 gauge and chamber length in mm.

Hey I have a F. Dumoulin & Co. 12 gauge side by side with double hammers. It’s complete. It’s very old but I’d like to know more about it. I’m a ypunger collector/gun activist. I live in Tennessee and would love help on identifying this gun down to the year and place made. I’m very excited and can’t wait for some replies. Thank y’all for your help ahead of time! I will have to upload some pictures later when I get to my computer. I’m very excited about this gun because I think the serial number is 106. I can’t find any other mumbers on the gun other than the multiple proof markings that I will post later. Please someone let me know that they know about these Belgian doubles! Thank y’all again!

outlawman7 - The reason for a lack of response here may be found in the post immediately above yours.

I have my grand dads Belgian Browning A5 Sweet Sixteen. It has a gold trigger and serial number starts with an x. I’m very curious as to why there is an “FN” above the serial #. Any help would be appreciated.

First Obligatory Proof Load for "Double-Barreled Breech-Loading Sporting Guns"
https://books.google.com/books?id=5fxGAQAAMAAJ&pg=PA53



It is not uncommon to see 2 bore marks, and .1 mm = .004" difference was allowed for the Second Obligatory Proof, and the barrels remarked.

Have a us arms Belgium, looking for info, reciever and barrel are stamped with 1563 has the circle elf star, has the Le peron, barrel ha a 33 stamp and an 18.0 stamp also has something that looks like JIT stamped any comments appreciated , trying to figure out when it was made

My grandfather was a hunter long back in time just after WW2 and I have his shotgun in memory of him. I recently decided to clean it up. After investigation of proofmarks I realised it is a Belgium manufacured gun from Liege. Quite old.







Maybe someone could determine year of production (I cannot determine is it letter d, j or delta in red encircled), manufacurer...

Some help:
S with asterix - inspector proof mark (C. Daenen) - 1952-68.
Jean Falla bore maker - 1931-53.
Greek letters are used - 1948-61.

I believe the lettre annale is a lower case 'j' without the dot, which would be 1931

Infro on Falla
http://www.littlegun.be/arme%20belge/ar ... a%20gb.htm

The gun has 2 1/2" chambers

Yes, it could be letter - j (1931).
But It is not going togheter with inspector proof (S asterix - C. Daenen, operative 1952-68).

One more question ....I have checked all markings and I couldnt find manufacurer signature. There are only proofmarkings of all kind. Is there any chance to determine manufacutrer at all ? ...

Where did you find the Falla mark? If 'JF' it could be Janssen Fils or Frères
There appears to be a mark forward of the flats on the R barrel - ?PM
Inspector's marks can not be used to date guns - the significance of some has been lost and they were re-used over time.

Yes - JF mark,.... I connected it to Jean Falla...
You are correct - there is another marking, but I have to check it at home...


Maybe RM

It is RM

I can't ID the 'RM', who was likely the barrel maker. I suspect the gun is a Janssen.
Cornell Pubs has 1926 Janssen Fils

and 1948 Janssen Freres repro catalogs
