Hello!

Recently I acquired a short double barrel hammer shotgun and I cannot find out its manufacturing date nor the manufacturer. Or rather, I know the manufacturer since there is a tiny stamp on the side of the barrels that says ''PIEPER'', but the only information that I could find is that it was a Spanish or Belgian (?) manufacturer, that's about it.

Is anybody more knowledgeable on this subject?

Here is the gun, which is actually really nice.

It has a greener bolt, 2 real side locks with hammers, it is chambered in 12 gauge (12 3/4) and coach gun-sized, but is has chokes.
