Black powder proof is available to this day at the proofhouse in St. Etienne. The only smokeless powder listed above is PT, powder PS is a semi-smokeless. Regular proof with smokeless began in 1900, but, it was/isn't the only level of proof available, even now.

I think we need to see the flats of some more guns before we can make the call. I was told the Lunettes guns were black powder only proofed by a French firearms dealer in Lyon. He didn't have any I could look at at the time.

A good friend owns a number 6 Ideal, I think, with a regular trigger guard, in 16 gauge. Wonderful gun that fits absolutely nobody who walks upright, and choked impossibly tight in either barrel.

Smokless proofed, however.


Best,
