My CMP pistol (R 244181X) came with the MB stamp on the frame, slide and barrel:

Frame and slide: in the sunlight, you can see that it is an MB on both.

The barrel stamp is harder to read.

The frame is also electropenciled OB83. It seems most of the images I've been able to track down of the MB (or M-B) stamps have been on pistols with an "O" electro pencil mark on them.

There was another poster who said they had a MB stamped 1911 (M-B slide, MB on frame, marked OB84) as well; links were posted in the picture thread.

In researching what I got from the CMP, this MB stamp is the only thing that has me puzzled...
