Hi TSI I don't know a ton about origional rifles but I am afraid you have one. A picture that also shows the whole rifle will help identify it.

I will direct you to a site called Muzzleloadingforum.com and have you sign up and ask in a coulpe of the forums if anyone know what you have. A warning though although we can talk about any m/l here you can only talk about traditional guns there. I still visit the site quite a bit though nice people for the most part with a few well I would not consider camp company.

I did not notice a date on the rifle or do I know whether or not it is a flinter I would sugest using the flint or percussion forums which ever applies or even the building bench those guys know a ton about the real deals they build replicas.

I look forward to finding out what it is I will look for your thread on the forums. If anyone knows what it is it's these guys.
