No #1, that particular gun came in cardboard box. No #2, yes you can track down a 22 mag cylinder for that era. The early Rugers with mag cylinders were called Convertables, but the 3 screw Super Single cylinder will work also. Know nothing about new model Ruger SAs, that where my Ruger Smarts end. Price looks to be in $400 range.

 

Back in the day Ruger would retrofit magnum cylinders to Single Six revolvers with serial numbers higher than 150000. Your gun is lower than that and looks to be from 1957 and did not come with a magnum cylinder. These guns have a bore sized for .22lr, not WMR which is slightly larger.

 

22LR cylinder is good enough. Make a low offer for time being.

 

Thanks guys! The guy is asking 575. So he is pretty far off. I may make an offer.

 

The serial number says the revolver was made in 1957 and will have a .222 bore as were all Single-Six's made before serial number 150,000, when the 22 WMR was introduced in 1959 and all SS have been .224 since

 

$ 575.00 is high but not bad when you consider the prices of new ones that have no where near the quality and collector value . I would buy it for 525.00 if it s condition is really nice.

 

I have found the difference in bore diameter of .002” has no effect. I have exactly same gun and couple older. I put Super Single mag Cylinder in it and it worked fine without any fitting. I do horde Ruger cylinders and sometimes have to go through them to find one that will work with out fitting. I have brass rod turned especially for OM single -6s.

 

Ruger would not (and still will not) retrofit a 22 mag cylinder to these early guns because Ruger has always considered the .222" bore size to be too small to safely fire 22 mag rounds. On the other hand, we Single Six fans like that true 22 LR bore size on these 50s guns. That's generally considered a plus for shooting 22 LR.

Your call, but I'd leave a 50s SS as is and just enjoy it. If you really want an Old Model with the later convertible extra 22 mag cylinder, they are still around. Picked this '65 vintage convertible last month for $360, with box and papers and extra cylinder. They generally run a bit more, yes, but there are still some good deals to be had.

 

Excellent buy of a very nice Single-Six
I don't think Ruger began using a prefix until after GCA-68
This link says your SS was made in 1969.

It’s worth more without the transfer bar retrofit. And, it will have a nicer trigger. Just carry the hammer on an empty cylinder. Nice revolver.

 

$575 may be just a little high . $450-$500 probably high retail with no box. Is it unconverted ? If so , Conversion lowers value.Nice looking old model .
