Proof, L4A2 & L5A5

Does anybody know what the markings: PROOF, L4A2 & L5A5 stand for?

What would the L designator for Round 1 the Rubber Bullet dated 1971 be?
"Proof" means a high-pressure load used to test the strength of the gun.

The L numbers are the official British Army designations for military equipment of a particular type. So the first baton round would presumably have been the L1A1 (although not all given L numbers necessarily see service). A slight modification would make it L1A2 etc, while a major change in the design would produce the L2A1 and so on.

That's how it's supposed to work anyway. Don't ask me why they jumped from the L21A1 to the L60A1 :tinysmile_eyebrow_t
