Mystery round

[SG500]

This one sold on e bay in May 2006 for 536 (not to me unfortunately).
I've never been able to find out any more details about it.
Does anyone have any ideas?
Presumably at least 2 people did as it sold for so much

Interesting

Well, here is my 2 cents for what its worth....

AUX = POLTE, Madgeburg
43 = 1943
the bottom number, I would suspect is a lot number.

As to what the case is..... I think it may be an experimental squeeze bore ammunition cartridge case....

or.... something someone has made up.....

Any dimensions??

(Just a ball o' help aint I :angel: )

It might be a percussion charge for a piece of super-heavy artillery.

Thanks for the ideas guys, no dimensions but you can see someones fingers in one of the photos that give a very rough idea.

Anyone else any ideas? Clearly a rare piece. Who knows, perhaps someone on BOCN owns it and can help enlighten us as to what it is?

Cartridge..

Could it be the following: "Cartridge, Machine, ball, .4 inch, Mark I, Solid Drawn Case", which was fired from the patterns of the Gardner machine gun?

Just a guess.

This case is an extended and necked down 37x250R Pak. The 7302 referrs to 37-20 what is the caliber - here 20mm.
Same designation is used on the Patrone 318 = 13-8 and on the 28mm sPzB 41 which is the 8202 = 28-20.
Hard to say if it was only for squeeze bores since the caliber coding was eventually used on full calibers (318) and also on squeeze bores (8202).

There exist two more of these cases with exactly the same hs, one empty and one with a HE shell on it what is puzzling since the caliber coding was used so far on primarily AT cartridge designs.

Thanks for the additional information EOD.

exact, but the shell caliber seems smaller than 37mm

kz11, check my posting, I mentioned there that it is 20mm.
