Hello, all. My first post here, hope it could be of help:
A couple of days ago I saw a topic started by Schneider looking for pictures of boxes of 7 mm ammo with a M as headstamp. Sorry for taking so much time answering, but finally here is the picture of the two boxes, one of 100 and one of 25
And here go another boxes, from the same period:
first: a 7,92 mm (steel core) close to a 7 mm M:
Same boxes opened:
Now, a box of 7.92 mm tracer / piercer:
And finally a box of 8 mm Lebel
I’m not an expert at ammo, but IMHO, the five boxes carry a label with the same type of letter, and the way they were sealed is almost identical. Moreover, if you look at the second picture, the multi holed piece located at the bottom is the same in the two boxes. Maybe this could indicated that all boxes are Spanish made for foreing ammo.
Anyway, the M ammo, in 7 mm, was one of the best ammo used during the war, and is still one of the most wanted to be shoot: reliable and no misfires after all those years.
