55 x 223R case??

[hicky1300]

Have been searching all morning so now resorting to you guys.
Picked up 2 very good condition brass cases.
Measure 55mm x 223mm. Rimmed with no headstamp.
Pressed in percussion primers.
Dia of rim is 68.5mm+. dist from top to start of neck is 33mm. Base to neck 80mm.
Unable to post pics as will not download & as yet no-one has enlightened me as to what I am doing wrong??!!

I think they are 57x225R70 cases for the 57 mm Nordenfeldt. They have been used by Germany, Belgium, Russia and the UK. Belgium cases are typically marked ("EP" and a 2-digit mark for the year of manufacture), the others I am not sure about.

I agree: I also have the rim diameter for this case as 70mm, which is near enough.

It seems to have intended for a casemate gun, but I believe that this was also the cartridge used in the German A7V tank gun of WW1.

There's a pic of my case on the far right here: http://www.quarry.nildram.co.uk/Tankmisc.jpg

Cheers gents - must recalibrate the tape measure!!
Certainly looks good as the 57 x 225R.
As I said no headstamp markings at all & they have not been ground or polished off.
I do not have one in my collection so for me a good find.

Here my 2 complete Belgium cartridges with emptied canister projectiles. Belgium used them as Fortress Guns.

BTW: they are up for trade (large bore WW2 cases) :tinysmile_fatgrin_t
