Wish I could help you out. I would have to dig mine out of the safe where it sits. I believe it is Uberti but mine is .38 cal. Bought it to use for cowboy action shooting but decided I had too many hobbies going on.
Do you want the Millennium finish as the one pictured? If so, bass pro usually carries then. Higher grade finished can be had also. But usually thru Texas jack (Cimarron). Don't over look hawes and other 1960-70s single actions.
