I have not seen E.C. No. 3 specified for smokeless proof, nor do I recall loading data marked on a Belgian gun



Raimey did most of the deciphering, and more educated thoughts would certainly be appreciated!

Bore 17.0mm = .669”
Right choke 16.9mm = .665” = Improved Cylinder
Left choke 16.4mm = .646” = Improved Modified

It was proved with E.C. No. 3 : "New E.C. (Improved) No.3” was introduced in the U.S. in 1904 and was 11 grains = 1 dram equivalent; 33 grains = 3 Dr. Eq.

Pre-1924 16g service load was about 1 oz. / 2 3/4 Dram (1220 fps). (4.9 grams = 75.6 grains = 2 3/4 drams)

Load markings??:
81 may be grains of black powder = 3 dram
50 “plombs” (weight) may be 4.9 gram Bulk Smokeless powder = 2 3/4 Dr. Eq. (50 grains = 3.24 grams so that doesn't work)
24 is likely grams shot (about 7/8 oz.) OR 24 grains = 3 Dram Eq. of Ballistite Dense smokeless

Drew, according to Lee Kennett's list of Belgian proofmarks, load data as seen here was only an official proofmark from 1897-1903. Can't say I recall ever having seen it on a Belgian gun either.

OK, a few things;
poudre is powder
plombs is lead
The crown ML is for Manufacture Liégeoise of weapons with fire, a very large factory operation in Liege.

I have seen the EC markings before. They appear on guns made just prior to WWI. This was the period known as the "German School". The Germans were pressuring the Belgians about their proof house. In fact they were trying to decrease Belgian exports so they could step into the market place.

In the end WWI put an end to that. The Germans did work many of their people into management at F.N. shortly after the war.

Hello:

I can not help with other marks, but about the load ones:

Poudre means powder and the weight is 0.81 grams
Plombs means "lead shot" and the weight is 24.5 grams.

0.81 grams is equivalent to 12.5 grains
24.5 grams is equivalent to 0.86 ounces.

Regards,

I'm confident it is 1.81 Grammes of some Powder & 24.50 Grammes of PB. I've seen it several times but will take a bit to locate the images.

Thank you Larry and Pete.

I'm postulating that the "poudre" specified is 81 grains (3 Dram) black powder. 50 grains of "E.C." is 3 1/2 Dram Eq.

Why would a 70mm chamber 16g (image on the original ShotgunWorld thread linked) be recommended for only a 24.5 gram - 7/8 oz. load of "plomb"?
Ballistite was the only Dense Smokeless in which 24 grains = 3 dram equivalent. Mullerite was marketed by Louis Muller & Cie S.A. des Explosifs de Clermont, Liege; No. 2 was a Bulk powder and 33 grains of Mullerite No. 2 = 3 Dram Eq.

Yes, proving with "E.C." was not uncommon, but I've never seen E.C. No. 3 marked.

Thank you Jose and Raimey.

New Schultze was 12 grains/drachm; close to .81 grams. But how many drachms in the load?

NO dense smokeless was dosed at 12 grains. Maybe C4?!? smile
