HUNGARY

HUNGARY_M70 front

Also known as the M50-65 by some authorities, it's a typical Warsaw Pact shape, though NOT identical to the Russian Ssh39 series.
Introduced in the late 1960s as a general replacement for the M50, which was a similar shell with a simpler three-cloth-pad liner and basic leather chinstrap.

HUNGARY_M70 side

Note the four low-set rivets holding the liner/chinstrap band.
The shiny surface is apparently an anti-magnetic coating; highly reflective, it was predictably unpopular with the troops, and cloth camo covers were usually worn.
