Two weeks ago I bought a ca. 1926 M&P in .32-20 (5"). It was non-factory refinished, but nonetheless a pretty good job, and in very tight condition with a perfect bore. Grips were period correct in fairly good condition and showing a few dings, but not much wear. I finally got around to cleaning it up today. I popped the sideplate, and it seems like the innards had already been cleaned and oiled, needing no other work. But what astounded me was what I found on the back side of the grips. First, they are apparently originals, as I could make out the correct matching first three digits (132xxx, penciled). Second is what was penciled on the rear of the left grip panel, a previous owner's name and an address in Albuquerque NM. The coincidence is that the previous owner had the exact same last name as mine. And my last name is not particularly common. So far as I know, I have no relatives in NM, all are back east. You never know what you might find in an old gun.
