Edmonton Area | Strathcona County | Double-barreled | Owner

Old damascus-barreled double barrel shotgun. Low power or black powder loads only. One barrel is 12g, the other has a 20g throat inserted by previous owner. External hammers and under lever, I think it is British make but not sure.

As New Condition, Full and Modified chokes, and will come with case

Pal verification required

I received this shotty from an estate.  I don't know much about these guns, more importantly value in current condition.   Can anyone offer any information, reputable links and approximate value(s).

Kind regards
