30mm

[CINDERS]

I have this Aiden (Not sure on the spelling) round marked J 30mm RG 00
Which I take as cal is 30mm R G = Radway Green and 00 as 2000 DOM
The J prefix denotes what! the type of shell it is like say H.E !

MkVII 303 for scale.

Here's mine, I had to make a projectile from aluminum because here in Canada...you'll never find an example live or just a good projectile. I saw a couple of VERY scrubby fired ones but those are unaffordable for junk. Being a UK weapon, they just don't surface here. Mine is marked very similar to Cinders'...

Looks the goods there Jim nice looking projectile you made up.

I had another real close look at mine again and came across these markings on the belted section above the web.

00, a dot, then GD, then 002
