30mm Aden HES projectile

[ken68]

Hi I Just picked up this Aden projectile RG 59 marked HES cant read what it says on the other side . it has a steel fuze plug . the HES filler has gone but has left a red stain inside . the fuze plug has 3 circles any idea as I have ECC shell case with the same, also an RLB case with the 3 circles . and a number 43 mk 2 B&B pimer ..etc ???? Thanks Ken

I am fairly certain that it means it has a Unified thread.

Thanks Guys ive seen it so many times on different shell cases , primers ,even a part from an old prac bomb I found . but never gave it a second thought. Until I seen it on the steel fuze plug instead of RG ?? . I am so used to seeing standard 30mm aden prac projectiles with alloy nose cones . I have seen a steel one on BOCN going have another look for it .. Thankyou Ken
