Oh, and are you absolutely certain all parts re Uberti?
for example, I have several Italian 1858 frames, more 1858 barrels, and with the plethora of makers the mix has confounded me.
ASM for example, seems to have offered "different " dimenssions, whilst Uberti changed dimensions at some year, Armi San Paolo
was at one time almost "inch-like" , and Palmetto was a creature unto itself .....
matching internals of anything before ~ 1985 or 1990 can be a nightmare....
that's why I had settled on "only Pietta Remmies" ... until "realy good impossible to pass up deals" overwhelmed my senses.
