Thank you Gentlemen.

You are both more knowledgable than I on this topic, but raise the same points that I have considered.

I had decided mid 1870s based primarily on the non-rebounding locks, centerfire cartridge, forend wedge, bore stamping.

Braddell stands by his dating, and suggests the possibility of a "conversion from muzzle loader"??!!??

Thoughts?

Aso what about relining the barrel(s)?

Thanks again.
