Not my area of knowledge, but as nobody has responded to your request, here's my take. The gun was assembled by an unknown maker (to me) using old parts from Ohio dealers. I think it is a nicely restocked rifle (due to the heavy use wear on the lock & barrel, but the fresh looking wood). I've added a bit of background info; more can easily be pulled up on these suppliers on the internet. Others may be able to assist you better if they decide to chime in.
