45x310R Soviet AT Headstamp


#1

What do the markings shown below on a 45x310R AT headstamp translate to? I know 184 is the maker’s code. The primer would be central between the two rows of dashes. The “184” is actually in a box with rounded edges.
Any info would be helpful.

220-----------(184)

42□-------------C

If it WWII stuff it’s Plant #184 in Zelenodol’sk (Tartar Republic), 42 - 1942, C - from the name of military inspector/ 220 -??

  • @ Falcon: I have 2 fired 45X310R AT brass shell cases of Russian manufacture from 1939 and 1941, both having the same headstamp style. “220” is the “Lot number” and the info posted above by “linnet” is correct. Liviu 07/01/08

Thanks, what does the small square after “42” mean?

  • @ Falcon: Normally after the two digit date of shell case manufacture [“42” in this situation] there is stamped the Cyrillic letter “G” which looks like an inverted “L” and has the meaning of “year” in Russian. Liviu 07/02/08

Thanks Liviu, I’ll have a look at the date stamp when I get home.
