While not originally "mis-marked", it ended up that way. Here is a Model of 1905, 1st Change, that was shipped in August of 1906. At that time, there was no address line on the frame. The 4-line address did not appear until after WW II. Yet this one has the 4-line address. Turns out that this gun was sent back to the factory for a re-finish in December of 1976. For whatever reason, some of the guns re-finished during this time frame received the 4-line address stamp. When Roy Jinks found out this was happening, he put an immediate stop to the practice.
At any rate, one does not see very many of these and when I saw it, I thought it would be an interesting addition to my accumulation.
The following comment was in a past thread discussing this practice:

It happened in the 1970s.
When a gun was refinished, it was disassembled by the Service Dept., including barrel removal. The Finishing Dept did not have the tools to do so. The rollmarks would have been added in the Service Dept. There are so few guns with the added marks that I suspect it was only one guy adding them and not all the workmen.
NONE of the guns I have observed had anything RE-stamped, IMO.
They only had the 4 line address added if the gun had nothing stamped on the lower right frame corner. If the gun already had "Made in USA", he did not add the 4 line address. As far as I know, S&W NEVER added the one line "Made In USA" stamp to a refinished gun.
They did NOT have remarked patent dates or logos. To remark those items, the old ones would have to be completely polished off, and it would be evident if that much metal was removed.
All of them that I was able to pull the grips from were marked with a date and refinish marks. I think they all had a star on the butt, but I do not remember for sure. I know some did. As I recall, all were dated in the early 70s, and 1972 is the only year I THINK I remember.
Roy was Production Manager at that time I THINK, not sure of his exact title/job, but he is definitely the person who ordered it stopped.
