Physically, looks decent except for the bluing being gone. You might asl on www.doublegunshop.com
in the forum section if there is someone within reasonable distance who can give it the serious going over IF you intend to shoot it sometime. As I said there are folks (Southern SxS Championships, Vintager Society, etc.) who do shoot theirs now and again, not necessarily in a duck blind, but at some quail or at clays for some fun and nostalgia. It all depends on the gun as each is different.
If you take the barrels off and look at the barrel flats and water table, see if there are European proofmarks. many times, guns of that era had barrels made in places like Belgium and there will be proofmarks giving chamber and bore size, proofed etc. If no marks, then they were made here. Might give you a little more history about the gun
