I got a fired .50 BMG case headstamped “S L 42” today at a junk dale for 95p. I bought it as it is a nice example with no dents and looks to have not been polished once since 1942. Not rare or anything, just a nice piece of WW2 history.
The only thing I noticed was that the bottom line on the “2” in “42” is missing. This looks to have been caused by a broken bunter. I imagine there would be millions of other rounds in existence with this error, as shutting down the production line during wartime to correct a cosmetic error on the ammo would not have been done.
Does anyone collect rounds by bunter/headstamp errors? I am not trying to sell this thing, but I was just curious if it is a known field, also does anyone else know of a “S L 42” .50 BMG with the same headstamp error?
I presume this was one of the many millions of empty .50 cases from US aircraft operating from the UK during WW2, of which there are a fair old few cases still around today. Apparently .50 BMG hulls were left here by the mound after the war, mostly dumped in the North Sea or melted down for scrap brass.
