At the time a whole number was desired over one of the "vulgar fractions"(13/1, etc.). And with the steel tubes & metal butt plate, it was not a conversion?


So if it was made as a muzzleloader in 1847 then it seems likely that it was converted between 1887 and 1904.

Can yall pick out any proofmarks from 1847?
