Does anyone know what the Belgians are saying when they say “Chambers proved 16/70” I ran across an interesting Belgian 16 bore and I am wondering what the proof represents. The gun is from 1943 with 2 3/4” chambers.

Thanks,

Good Hunting,
Mike

16/70 means 16 gauge with 2 3/4" chambers. 70mm = 2 3/4".

Thank You Gentlemen - I understood the 16 and I didn’t do the math on the 70.

Good Hunting,
Mike

I wonder what that gun was. Belgium was occupied by the Germans in 1943 - that was during the middle of World War II. I would not think there was much bird hunting going on in Europe them.

It is a Masquelier and the 1943 comes from the sellers description. I understand you questioning the date of manufacture. I have not seen the gun, just saw it online. It is a nice looking sidekick.

Good Hunting,
Mike

After the Liege 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, l2, 10, 8 & 4; 670 kg per square inch for sizes 20, 24 and smaller.”
600 kg/cm2 = 8534 psi maximum SERVICE pressure;
670 kg/cm2 = 9530 psi maximum SERVICE pressure
+ 10 - 14% by piezoelectric transducer measurement
SO 16g service pressure was about 9,500 psi

20 g was PROVED at 1000 kg/cm2 = 14,223 psi
12 & 16g PROVED at 900 kg/cm2 = 12,801 psi
Modern transducer numbers for 20g would be close to 15,500 psi; 12g about 14,000 psi

Drew,
Thanks for the informative post. It sounds like the gun would work with RST shells? I would need to restock the gun so I may keep my powder dry for another English 16.

Good Hunting,
Mike

Mike,
I like side lock German/Belgian guns very much. Some very high quality double guns usually at reasonable prices. I recommend the J.P. Sauer pre war Best guns with the Krupp barrels, the 16 gauge I picked up a few yers ago is a honey and I use the 2 1/2" RST or Poly SpredR's for Grouse and Woodcock hunting. Krieghoff pre war guns are world class guns also, with these kind guns available I would pass on the unknown makers. Some were very good gun makers however.

Mike,

On many older guns one will also see 16/65 and 16/67 at times, which corresponds to a 2 1/2 and 2 9/16 chambers, respectively. If a 16 has a 16/70 chamber from the factory, it was usually produced from about 1930-35 to the present, most earlier 16s had shorter chambers.

Some European doubles also state chamber, bore and/or choke measurements in millimeters. For example, the 59 Beretta Silver Hawk that I have gives 3 millimeter measurements on each barrel just forward to the water table, 18.6, 17.0 and 16.1/16.4. Multiplying by 0.03937 gives these measurements in decimal inches: Chamber = 0.732; Bore = 0.669; Left barrel = 0.634 (Extra full ? with 0.035 constriction), Right barrel = 0.646 (Improved modified? with 0.023 constriction).

European guns are millimeter friendly.

Dave,
I think Masquelier was a respected maker and they were around for about 100 years. They produced many grades of guns and some very fine sidelocks. You don’t see too many of them this side of the pond.

Good Hunting,
Mike

You should be able to tell the year of proofing - the Belgians used letter codes stamped near the proof marks.
Charts are here: https://www.shotgunworld.com/bbs/viewtopic.php?t=232252

Masquelier is/was a higher-grade manufacturer.

Gentlemen,

Thanks much for the education on Masquelier, I have heard of there guns but never knew they were a high grade manufacturer. Thanks for the education.

Thanks everyone for the info. I don’t think I am going to pursue the gun if anyone is interested. The gun is on the Dismal Armory website.

Good Hunting,
Mike
