Long rifle identification.

[kuriouskeepsakes]

I was hoping someone might be able to identify this percussion rifle. 45 cal. The only marking I see is a capital letter "L" on the inside of the lock. I haven't removed the barrel yet. Also, would you call it a Pennsylvania Rifle, or a Kentucky Rifle, or is there a difference?

I found this marked stamped into the wood on the inside of the patch box. It looks like "ON 24".

Any ideas? Age?
