Hello guys,
I recently got this 20x138B german Flak casing and it's a bit different, having a ring in the casing head around the primer. Note that this is not a ring close to the primer in order to aid in crimping, but it's at a rather large distance to serve this function.
Have you seen other cases like this? I have only managed to find one other example, made by "va" (Kabel und Metallwerke Neumeyer AG).
Thanks in advance!
