Opps!
My mistake on the safety hammer. Happens every time I post from memory.

I think all we need at this point are the numbers. Good photos of the barrel/latch numbers.

Without them I think we’ve reached a dead end.

Oh, barrel lengths are definitely not an exact science. Antique Smith & Wesson revolvers often see variance of up to 1/4”.

I like the theory that this might be a late assembled gun using up old stock. Very possible.
