The One I bought in Dec was $400.00 but it is a cavalry or 3rd model with fluted cylinder. it had never been fired but was stored badly in a holster for 50 years so pitted in places and a small bit of rust, but none in bbl, someone tried to clean up the outside of the bbl with steel wool it looks like, nothing a good re blue would not fix.
