    have seen flak type AP shells with two crimp grooves (only one used) and also PAK type AP shells with one large crimp groove.

    Hey,

    Thanks for your answer!
    Extraordinary that both types were used, ..that's a first for me!
    Do you recall iff the shells you observed, were fitted with copper or steel drivingbands? (I can imagine the ballistics being similar for the 3,7 cm Pzgr 18. and the PaK 3,7 cm Pzgr with the narrower steel drivingband).
    Was the usual BdZ. 5103 fitted to the shells, or the (KM) BdZ. 42a ?
    Were any pictures taken of the finds? Those would finally solve the mystery about FlaK M42 AP, as, to my knowledge, No original documentation on the subject has ever come to light?!

    Have to correct myself, all were Flak AP shells but with the difference that some of them had only one crimp groove (that's why I remembered them as PAK Pzgr., but they had the same length like the normal Flak Pzgr. with two grooves).

    The upper crimp groove was left on the shells with one groove but the grooves where different. Some had one deep grove with same shape as the Flak Pzgr others had one small crimp groove as known from the 3,7 cm PAK Pzgr at the same position. Cartridges with normal two groove Pzgr. were crimped only in the upper groove.

    All were fitted with Bd.Z.5103, all parts WaA stamped, no naval stamps. They had FES bands (1945 made so no wonder...). Sadly I am also missing the ammo manual for this gun it would answer our questions.

    Only found a very old picture of the "one large crimp groove" shell:
