At a local gun shop there were a couple 66s I was interested in. A 66-1 and a 66 no-dash. The no dash was of interest because of the SS rear sight. Both guns were mechanically fine. The guns were stamped with the LGS name below the cylinder on the left side. Asked the sales clerk about it. He said they are required to do this on all used guns. They even have regulations as to where each gun is to be stamped. I check out dozens of gunshops a year and this is the first I have seen this. It would ruin a collectors piece. Has anyone else ever seen this.
