Russian 23mm?

[orcutteod]

I'm pretty sure this is a Russian 23mm but wanted to verify it. The projectile is hallowed aluminum and is a little less than 25mm in diameter. So I guess it's a demonstration projectile.

It is near impossible to ID something in a down looking isometric view. Take a photo looking straight at the side of the complete dummy to show the correct profile.

That looks like a Russian 23mm. Projectile does look real.

Here's my 23MMs. Projectile profile is a little different from yours, but I'm sure there were many variations.

Slick I THINK yours where for aircraft or naval, I forget. The one posted is for AA.

Thumbed thru my SOVIET CANNON encyclopedia. Without delving too deeply into the text, it looks like orcutteod's shell may be a Czech "tool cartridge or chamber gauge". Pg. #147 of about 20 with numerous options/variations/countries of mfg. As for mine, I've not identified them any further than dimensions. I'd forget, anyway.

Slick yours look like 23x115mm for the NS-23 aircraft cannon. The one on the left is a "TP ballon round" and not sure of the other. This is from: http://www.russianammo.org/Russian_Ammunition_Page_25mm.html

It looks to be 23x152B Vya/ZSU 23 cartridge. Then it cannot be czech since this round was not used by Czechoslovak armed forces.

I believe Mr. Nabob is correct. Thumbing further thru the book, I ran across the belted(152mm) options and there is an example with the same headstamp, although the "A" (at 9 o'clock) is obliterated on the pictured example here. I could not find a chromed example in the book.
