"S" was the old way Ruger marked a "used gun" or "sample" gun. They did this at least up into the 1970's.
Then they started marking them with a "U". Then an asterisk, I assume because one factory employee told me point blank..."Ruger doesn't sell "used" guns".
Today I don't believe Ruger is marking them at all. They used to get a "USED GUN" stamp on the end of the box but I don't think they're even doing that now.

Usually now the factory is stamping 'UGB' on the end label which stands for Used Gun Bank...it is their used/seconds/sample gun listing that they maintain....
I have a few examples with the stamp and with out the stamp...not consistent like it was a few years ago.
