Looks like you have a Cimmaron Big Iron there - entry level SAA which seems to be retailing for a hair over $400. Pietta has been around a LONG time - damn close to Uberti in quality - just check timing and lockup and shoot it. With .38 Specials, it'll be a fun pointer/plinker with little recoil.
If it was me and you did get it for cheap, I'd strip that ugly black finish and give her a quick rust treatment browning and oil it up. Would end up looking like a period piece for little money! Just love those brass backstraps.
Then again, maybe you want to off-load it - I'm sure there would be some takers here on the Forum!
