Interesting crimp on MW '44 cartridge

[CINDERS]

The answer to the crimping question is in the answer below. Therefore the case at the start of this thread that I questioned is not dodgy nor been tampered with but part of a process evolution. Excuse the pic I had to use the computer and take the pic with my I-phone but it clearly shows the change as highlighted by the arrows.
Cheers

"Changes to .303 projectile material and crimping: from top cupronickel with neck staking into low cannelure phased out in 1942 to be replaced by gilding metal neck staking which was in turn replaced by mouth coning into a high cannelure in 1944 which continued until cessation of production. The mouth coning of the cupronickel projectile (second from bottom) in 1944 was to use residual ‘surplus’ cupronickel stock."
