I picked this 1971-72 Model 36 3" up off a local forum, had to drive about 5 miles to get it. , lots of holster wear to the cylinder and muzzle but nice and tight. Figured it would be a good truck gun. Today I won a Thad Rybka holster on eBay for $39. Didn't know anything about this holster maker but did some research and found an article about him and read where Skeeter Skelton gave him high praise many years ago. Thought it would be a good match-up. I'm not sure what MF stood for and kind of afraid to ask but I don't think anyone will be looking that close anyway.
