ruger old model single six serial numbers

Sometimes just drop in and sometimes too long (OK) or too short (not OK). (Any markings like numbers on the end of the cylinder?)

22 magnum cylinder is correct for the period. I bet you made the call to Ruger recently but more on that later. Anyone have a similar experience or suggestions on whether to try to buy a standard cylinder and have it fitted to this revolver? Anyone come across a good source for affordable 22mag ammo? But, it would be nice if I can also fit a standard 22 cylinder and use the less expensive 22lr ammo. 22mag ammo, I can live with it being mag only. Is this correct? If I can locate an adequate source for. 22 Magnum only (even though base does not say anything about magnum and the cylinder is totally unmarked). I called Ruger and they advised it is a 1965 produced Single Six Magnum. It now appears I had an old fluted (unmarked) magnum cylinder. However, something wasn't right when I loaded the first cartridge. Went about locating 22lr ammo and getting ready to go to range for first shooting in a very long time. I cleaned it up, did a quick web search and concluded I had an old single six convertible with a fluted (unmarked) cylinder - so must be the standard cylinder. Father didn't have the manual anymore and he had only one cylinder (he didn't remember if it ever had 2 cylinders, he got it in trade from a retired small town cop). 22 CAL SINGLE-SIX' with blackhawk logo and walnut handle. It is an old model 3 screw Single Six that has on the left side of the body 'RUGER. My father just gave me the old 22 pistol I plinked around with when I was a teenager (40+ years ago).
