does anyone know where I can look up types of guns. all I know is what it looks like. like I said. I did handle it a little but did not get to look at the markings.

I'll discribe it the best I can.
curved buttplate (brass)
brass trigger guard curving out wards
stock running the almost the full lengh of the barrel with a brass cap
where the nipple was, it was a round breech area.
did not see tangs.
the owner asked the gunsmith if it was a cva he said not but it is an a spainish barrel.

how that helps.
