This my first post on this forum, so please bear with me if this is an inappropriate place to post the question.

A friend has a nice, 1891 vintage, Lancaster Colindian. It's a WWII bring-back from Italy with an Italian name engraved on the trigger guard. I'd call it an 85 or 90 percent gun, certainly in the NRA Very Good category.

And I may have a chance to buy it. The trouble being, neither of us can find any resource that can give us anything like a current fair market value on the piece. Is there a resource somewhere -- heck even a current auction sale -- that might give us a line on a fair price?
