Very nice!Looking for some insight on these. Some look newer but a couple look old and clean.
Uberti .54 cal, Santa Fe, Lakeville, CT SN 10xxx

If I’m reading the two letters on the square box correctly, your Uberti is a 1993 model.
Verify the bore diameter, as these were marked .54 caliber but actually require a .520 ball. I don’t know if this was changed on later guns like yours.
