with it, I would still contact the factory to see if it was shipped as SC6 or SC6M.Īt least 15 SC6M were produced for a distributor. If it was shipped as a convertible, then Ruger scratched the front of both cylinders with the last three digits.īut if it only has a Mag. only, the last three digits of the serial number should not be scratched on the front face of your cylinder. cylinder with it or is it a convertible? If it was shipped as Mag. So I really think Ruger's box printer got their line-o-type mixed up between box printings. There are also a very few of those known in the early 20- prefix. CALIBER REVOLVER' which had been printed with that since the mag. A few earlier than that serial number range are also known to have been shipped in that box as are a very few with a 60- prefix.Īt the very same time, Ruger's RSSM printed 2-piece box for the fixed sight model began appearing with '.22 CALIBER REVOLVER' printed on the end instead of '.22 W.M.R. CALIBER REVOLVER' on the end instead of '.22 CALIBER REVOLVER'. In the 560xxx to 566xxx range the SC6 box started appearing with '.22 W.M.R. That being said, the maker of Ruger's two piece boxes also made a printing error, and it just happened to occur at about the same time the SC6M were produced. The only one that had been known was 555430, however we have no idea of the whereabouts of that revolver today. there were indeed at least 15 of the model SC6 Super Single-Six with 6-1/2' barrel shipped from the factory as. The MK-I will have the small size serial numbers and the Standard Autos will have the large size serial numbers.Yes. Some of the guns got out without the 'D'.

This also happened when they serial numbered MK-I in the 300,000 serial number range, and when the Standard got to 299,999 they continued numbering the Standard guns in the 300,000 range. That is why your gun has the 'D' stamped as part of the serial number. After they had serial numbered a few thousand, someone at the factory caught the mistake and had a 'D' put on the serial number. This was in 1968 and the factory forgot that in 1965 they had serial numbered Super Single Sixes in that range. When the Single Six got to 499,999 it went to 500,000. The super Single Six was assigned the serial number range 400,000 only 5 were made with that serial number 400,001-400,005 and the 500,000 range. And the Single-Six like yours and the Super Single-Six. They did he same thing with the Single-Six and the Light Weight Single-Sixs. They did the same thing with the Standard Autos and the MK-I. Ruger has the policy of setting aside serial number blocks for different model guns. The Super Single-Six that has the same serial number that your gun has, minus the 'D' was made in 1965. Your gun was probably made around 1968, a call to Ruger will give you a shipping date. It's a Single-Six in the Super Single-Six serial number range.
