Need help IDing two mystery empty cases

[svt-40]

Left to right: mystery case 1, mystery case 2, 7.62x51 NATO.
The #1 is the longest, I have two identical cases with different headstamps:
one has 11 on top, two 5-stars and 52 at the bottom
another has 11 on top, 6-star on the left and 50 on the right and a female ### symbol at the bottom.

The #2 is a tad shorter and marked 8 on top, D A and 78 at the bottom.

You need to take better pics of the headstamps, and larger.

Get a metric ruler and tell us how long the cases are.
The 762x51 would of course be 51 mm long

7x57 and 7.5x55?

11/**/52, should be Yugo, 8mm Mauser, from 1952, the stars denoting military ammo.
Your next is Czech 8mm Mauser, and besides the female symbol there should also be a slash mark, 1950 again, and IIRC one flash hole if that slash mark is there.

Your D-A round is Swiss 7,5X55.

There is a kind of slash mark, but above the 6-star

Hey Guys; The 7.62x51 is the military designation for the .308 winchester round which was implemented as a military cartridge in 1952.As for the rest you need to give some more info...
