What do I have?
7.65 Luger ?
Case Length 21.43
What you have is a 7.65 mm Parabellum (.30 Luger) cartridge made by the Deutsche Waffen- und Munitionsfabriken A.-G., Berlin-Borsigwalde factory, for the Portuguese Government. The identical headstamp also appears on steel-case 9 mm Parabellum. One of the standard pistol cartridge of Portugal was 7.65 mm Parabellum, used in Luger pistols also made by DWM, although by 1941 I believe they were beginning a transition to the 9 mm Para cartridge and pistols.
Yup, that’s what it is. You got a fairly scarce headstamp.
So the 41 is the date and not a DWM number? What does the B B stand for ?
Recently, a similar cartridge was sold in Germany.
But this cartridge had a black case. Or is it the patina?
I personally think, from spots on the projectile, that the cartridge sold is simply in poor condition. I think the black is simply the patina of corrosion.
Normally, with the K DWM K 471 and K DWM K 471A headstamps, the black case means a load specifically for the Luger Carbine. The round in question is certainly not that!
