Help with assembly stamp, before I bid.

[69L72RS]

Hello,
I would like to get some opinions on this assembly stamp before I bid on this item. My concern is over the "M" in the stamp. It doesn't match any of the other "M"s I have on file. It is wider, by measured percentage and the center is to high in relation to the two side legs. Also the letter looks to be not as deep as the "N" or 2's.

I have compared it to earlier and later built stamps, which match each other and it is not like any of them.

Does anyone have a match to the stamp font on record?

Thanks for your help in advance.
