Russian Ssh40 helmet (part 2).

Continuation from  Russian Ssh40 helmet part 1
What I like about this helmet are the many stamps and inscriptions at the inside.
Information on worl war helemts.com tells me P = POCT means size.
Size 1 = Small
There where 3 sizes: 1 = Small 2 = Medium 3= Large
Ct = manufacturer Stalingradskiye Traktorskiye
56 = year of production = 1956
Besides this stamp, there is a stamp telling this helmet is accepted for servie "46".
There is also a lot code 1 - 1138.
 
I found additional information on the Stalingradskiye Traktorskiye  at: https://en.wikipedia.org/wiki/Volgograd_Tractor_Plant
