Since no one else has chimed in...
There was a time before Smith and Baker went their separate ways that guns such as yours were made in Syracuse. While there's no doubt a relation to the somewhat later L.C. Smith (and obviously Baker), I think I'd probably consider this gun to be a Baker and not a Smith.
Anyway - Stub twist indicates one of the lower grades of damascus-style construction. Thus, I expect a field gun. I'm sure you're aware that such firearms were never intended for nitro loads and may not be safe for any load at all after more than a century.
Depending on your intentions a firing pin can easily be made by almost anyone with a lathe. I rather doubt that one will be available from a commercial source.
Murphys Oil Soap will work well on the wood and will not harm metal components. If the gun is in any kind of condition at all I wouldn't attempt more than a good cleaning. More than that will have the potential to ruin perhaps 130 years of history.
