I think those proof marks are from Belgium?
Looks like 2 3/4 12 gauge 12-70 (pic is small)
and based on what I think the proof mark is I think it was proofed in 1977? Probably by Degrijse Pierre
Its definitely got the 17600 psi (nitro) proof
The D with a crown over top just forward of the flats would seem to be an inspectors mark, but I cant find a reference to it.
It seems to be a modern boxlock gun, made to look like a damascus sidelock gun? The rough finish in the non visible areas is common on guns made in Belgium. It is likely not a top quality gun, (compared to the worlds finest guns) but if it fits you, and the price is right it will provide many happy hunts for quail or other game.
I will leave it to the experts to tell you what I got right and what I got wrong.
