this is the good side of my 32-20 SN.9830x The other side is the confusing one.

This side shows what happened if you sent your gun back to S&W in the 1970's.

Yes - that was SOP for some number of years. Roy Jinks was able
to put a stop to that, when he found out about it.

I think the factory believed that the service depart should bring
a gun up to current specifications, and apparently roll markings
were part of those specifications !

There were several guns like this offered at an auction last year.
It was very confusing, at first, to see very early guns with very
late markings.

I learn something every day on here, Thanks Mike.

I bid up an Army marked 1917 .45acp that had those roll stamps on them. That was before I learned that it was the rule for guns returned to the factory for repairs. Didn't win the auction.

I've never seen that before either - thanks for sharing.
