Ted, thanks for the Darne background and you are indeed the Darne expert. And thanks GLS for the Darne SN list. Here's a question for Ted. There are two Darnes pictured above with SN's that are very close.
-- C692, a 12 gauge with a chamber stamp 6.5".
-- C643, a 20 gauge with a chamber stamp "70".

The two are post 1910 because of the letter/number SN per GLS's chart; C692 with the cm chamber stamp would be between 1912 to 1910 assuming 1912 was indeed the changeover year in Saint Etienne from cm to mm, could it be that both of these gun barrels were completed in 1912? Perhaps the chamber size wasn't stamped until the barrel was mated to a gun, which might explain why the 20 ga has a lower SN but has a chamber stamp in mm?

It would also mean that Darne built some 2,700 guns between 1910 and 1912. Is this possible?
