T58-

It's a Tolley from ~1883, 500-450 3-1/2" Magnum BPE (NA&A)
The forend is held with a wedge, as it was the day it was delivered.

Lagopus, just as I cannot prove that the shotgun in question is definitely a conversion from pinfire, there is no way you can prove that is not.

There is no Certainly with that piece...
