And while we're at it...this is from a St Etienne Damascus barreled hammer gun 16 gauge...no photos of barrels flats, etc. but what powder is this proofed for? Can't make it out. PVI? PM?

And this one. Manufrance Damascus barrels - chambered in mm 75 - 14 gauge (it's marked 17.4 - a little larger than 16 gauge - but the sellers states that 14 ga shells fit the chamber - he has 30 of them.) Has to be between 1885 and 1889. But what is the "F" proof mark?

And final question: 16 gauge Saint-Etienne top lever hammer gun with poor photos...but it's proofed for what? PS is obvious...but again PM? PI? PVI?
