So, we look in the RENE Guide, under the Single-Six Convertibles, and the list of serial numbers, by the years, allows us to say your gun was made in 1967. If your gun had the adjustable sights, it would be a 'Super Single-Six Convertible.' The Magnums were dropped & Convertibles were offered. It was because folks were asking for the other caliber for their guns. In 1959, the Magnum Single-Sixes were produced, and later on, when they decided to make just one model, they made convertibles. Any fixed sighted Single-Six with a serial number before 150,000 did not have the mag cylinder. The number places it in the production era after the magnum cylinders were being added to the Single-Sixes. So, as you already know, your gun is a FIXED sighted gun, and that makes it a 'Old Model Single-Six Convertible.' It's not marked 'magnum' or it would have a different serial number block. MUCH better than any other resource for us. You can join RENE, and Chad (chet15) has a Reference Guide that is INVALUABLE to collectors. It really doesn't matter, since The Factory didn't record all the individual bits used on any particular gun anyway, so there is no documentation for most of those with the possible exception of some particular grip frames or panels, and these only occasionally.Īll this only serves to keep us on our toes and remember that with Ruger, never say never.As FM alludes to, we use the RENE Reference Guide for information. There is no real way to sort these aberrations out, but in most cases they can be identified as 'suspicious' if that matters to someone.

And of course there is always the potential for the 'screwdriver variations' arising from easily-swapped parts that muddy the gun's actual date of origin, either 'early' or 'late'. There will always be the occasional 'late shipped' gun having bits and pieces that were released considerably after the gun's serial number might indicate, or the occasional gun wearing some older bits from way earlier production that just floated to the top of the 'parts bin' at final assembly. He can, for instance, occasionally come pretty close to revealing within a month's time when certain features/parts were changed in a run of a particular model. His serial number breakouts are considerably more precise than anything Ruger has put out, and his discussion of which parts were used when is further informative. Knowing the month as well as the year certainly helps since the various 'type' configurations of many of the Old Models are pretty well known and documented in Chet15's Red Eagle News Exchange Reference of Ruger Firearms.
