Mossberg 42MB(a)

[sakorick]

The right letter should be a B. The left letter is probably not a L. Can you look with a glass? The 4 is the inspectors mark. None of the apertures were marked, however, it makes not a wit. Many of these Receiver sights were replaced with Parker Hale sights which IMHO are not as nice as the good old #4 Mossy! You should report this rifle on the Mossberg thread of Rimfire Central. I am collecting data on these guns for the Mossberg Collectors Association. With your permission, I will post your rifle in the next quarterly newsletter. Regards, Rick.

I have attached a photo of the mark, the left letter could be a "C" but is not well struck, the right letter is definatly a "B". Please feel free to use any information of pictures, I think I took all of the relivant ones but if you need any more please let me know. Sorry about the grainy appearance of the picture but it is the best I could get it to make it readable. Paul

Your rifle was proofed in 1953 and that is consistent with many of these 1950-1954. I'll include it in the survey. Thanks a million. Regards, Rick.
