Reprimed? or just Badly double-struck originally???
From the photos I can’t see any evidence of repriming, as I would think it would be close to impossible to “re-crimp” the primers close or identically to the original (RWS) primer crimp. There would always be evidence of the original crimp (even if swaged or “reamed” out)…I know, I reload a lot of (1930s) German cases for use as Blanks (Film work).
Of course, from a close look, they could have been “Recapped” because of faulty primers; but by the 1930s, “re-capping” was becoming a lost art…it was prominent prior to WW I, but the economics after WW I, made it a “no-brainer” unless we are considering Millions or tens of Millions of rounds. And for simple ball ammo, I would not think so.
Also for German late 1930s productrion, which was very high quality, even after dubiuos storage, I would doubt that such large quantities were “failing”.
One solution is that Germany also supplied Spain with large quantities of Once-Fired Brass, for “Reloading” as Spain ramped up its 7,92 production after the SCW…a possibility— and that Spain simply didn’t recrimp the reloads.
The original RWS Export Pack shows that either the ammo was repacked or that empty RWS Boxes were recycled after the loose ammo was either belted or clipped up for distribution…re-use of packaging was still a feature of 1930s-40s Armies.
In any case, such recapping etc. would be noted on the packets, at least on official production…Has anyone though this may have been Republican recycling during 1937-39?
