I just acquired a Ruger Old Army at a gun show fo what I think was a good price, $300. The bore is excellent, It has replacement Walnut grips and a replacement rear sight with a narrower notch. The box, manual and original grips and sight were included. I just needed to order a nipple wrench. I have a couple of questions that maybe someone can answer;

1 I know they haven't made these in a couple of years so it is not new. The serial number is 140-156xx. Can anyone give me an estimate of when it was made?

2 On the front face of the cylinder there is what looks like a tiny "S" and a script lower case "g" electro-pencilled. Anyone have any suggestions what they could mean? I guess one of them could mean "don't load this cylinder", but it is hard to figure out which one they are referring to.

Thanks

Looks like 1974. It is an early one.

For a nipple wrench I have a 3/16" deep drive socket wrench that I use.
Works great with the factory nipples.
If you change the nipples out to Treso or SlixShot nipples you will need to use another type of wrench.
