(PL) 26mm signal ammo -polish - headstamps

What do we know about marking Polish signal ammunition in caliber 26mm?
It seems that everything.
Simple repetitive marking the same for many years:
@12h code producers caase in oval
@6h two digital code years production case

Used from c. 1953 to 90’s like this:

Przechwytywanie1

But before 1953 we have most interesting HS like this:

from unknown producers with code (26)
Przechwytywanie2
Przechwytywanie3

and from (361) on another orientation code
Przechwytywanie4

and from new production :

Przechwytywanie5
