They both should be on Ruger's web site. Think that 22 Mag is early 60s.

With a 6 digit SN# 489960, there is no way possible for that gun to be from 56/57.

I'm not sure but I think you have a LR/Magnum Convertible and your missing one or the other cylinder.

A call to Ruger might tell you,,, BUT $10 to Ruger will get you a letter with the details.

Ok. I see I was not counting numbers. What is the difference between the two I have. The 313042 has magnum on it and the 489960 just says single-six on it. I'm trying to learn something here. I have ever had that had the drift adjustable rear sights. I have another 3 screw with fully adjustable sights. I'm 72 and have been shooting since I was 7 yo. Still learning.

never too old to actually read the books and still learn,just what is wha,t and why...bottom line quickly is the #300000 serial number range guns are started when the 22 magnum caliber became ( was born) developed around 1959.......Ruger made the 6 1/2 in barrel version,, marked the left side with the 22 magnum rollmarking .....was another Single Six model in the different caliber ...in a short while mr Ruger figured out why make two different guns, just combine them to one, and add, or make available, the spare cylinder for the 22 caliber ( shorts, longs and long rifle) save time effort and money get the same thing done voila cost savings remove redundancy etc......., why not continue to make ONE revolver, the Single Six and add the 'Magnum cylinder to it,,,,,hhhmmm.he was always doing things like that, his mind always working the angles and be one up on the competition..............I for one respected that and loved to speak with him as to the whys and the wherefores, BUT he preferred to speak about 'family', with my wife Laura, we'll never forget when he, and my wife and Hank Williams JR., were sitting together at the NRA convention at the Ruger booth, along with Roy Jinks from S&W, and they talked about kids ( children) as at that time Hank was a "new " father and and I believe it was a little girl......everyone else there was wondering just what the hell they were sitting there and talking for the longest time and it was NOT guns, or business.........true story;)

Well, I found out while cleaning them they both have the magnum cylinder in them I have a extra long rifle cylinder. How can I tell if it's a new model or a old model. It is a hair longer than the magnum cylinder. I can get it machined to match the magnum cylinder.

I have found these tables to be mostly accurate- but RENE tops all.

I have also been on the lookout for a WMR cylinder that does not have the last 3 of the serial inscribed into the face. eBay seems to be a plentiful source of cylinders, but also a plentiful source of inadequate or indirect descriptions. Maybe someone can confirm or disprove an observation-

New model cylinders seem to have a slightly smaller star wheel diameter along with a different cutting method. This appears to manifest itself as a slight notching of the star wheel on the OM cylinders that is not present on NM cylinders. All my OM cylinders show this notching, whereas my 2 NM cylinders and all online verifiable cylinders don't.

This is the NM WMR cylinder. The cylinder shoulder is cut right up to the edge of the star wheel.

This is the OM WMR cylinder. You can see the slight crescent notch at the shoulder of each cylinder. The star wheel on the OM measures .6215, my NM measures .6210
I believe the notch is caused by different tooling as opposed to the slightly larger diameter- or maybe by a combination of the two.

Anyways- occasionally there are cylinders described as NM .22LR cylinders. But they have these "notches". I'm guessing they are possibly OM WMR cylinders. Thoughts?

the the cylinders may have some numbers etched into the end of the cylinder, and the last three digits of either gun will match the cylinders numbers, possibly that will tell you which goes with what gun.....you know the one Mag cylinder goes with the 'Magnum ' marked Single Six and if it was a single cylinder gun, ( some later ones were shipped with the extra cylnder and in the case of the Magnum marked gun ( the#300000) gun the spare cylinder is a 22 cal ,short,long,long rifle,,,,and the other gun ( #400,00 serial number range) the spare cylinder is a "magnum", hope that comes across clearly..........most of us could tell you in a glance if we were holding ,looking at the two guns and all the cylinders...........:cool:;)
