Not really sure but on those early central-fire breech-loaders, there was only a single proof on one tube noting proof of the whole lot? I believe that changed with the 1888 rules. If not in 1888, then for sure in 1891 followed by an addendum in 1893 forced by the hand of the Germans.


>>A Lefaucheux double-barreled shotgun would then carry these marks

a) temporary proof mark for single barrels, the intertwined EL.

b) the final proof mark of the barrels, already regulated and soldered, the ELG in "an" oval.

c:) after fitting the barrels and fitting the action, the finishing the gun, the Perron, the final proof mark is applied.<<
