Reck R12 .22 issue, who for handgun smith?

[Redneck 7]

I acquired two Reck R12’s, one is a single shot and one is a 6 shooter, in a horse trade deal. Turns out the guy in BC sent me the one 6 shooter he had that doesn’t function properly. He had 3 in total and sent me two, then he said if I got the broken one because he didn’t know which was which of the 6 shooters, he’d send me the 3rd because he never uses them. Well I got the broken one and he’s saying he’ll send me the parts he replaced and didn’t put in and blah blah. I’m just upset I can’t use my new to me revolver.

So who in the Edmonton (area) is a good gun smith to take this revolver to? The problem is when you cock the hammer, the cylinder doesn’t cycle to the next chamber. I’m not very knowledgeable when it comes to taking apart and fixing revolvers just yet. But I’d like a smith to look this over. Thanks for any help and opinions.
