Wiltshire Arms Co. DB Shotgun Worth?

I just got a old double barrel shotgun made by Wiltshire Arms Co. On the barrel it says "genuine laminated steel" and "choke bored" Its in pretty bad shape, lots of rust, both hammers are missing...but would probably make a good wall hanger once cleaned up. Does anyone know anything about it, when it was made or what it might be worth? I can't find anything on it. Thanks!
