Nk - cartridge case for
57 PLK S60 - 57mm AA gun S 60
Nc 7...type of powder
powder manufactured in Synthesia Pardubice series 4 year 1960
A nma.. black powder manufacturer and decoppering wire (Pb)
Fl - flegmatisator

4-61 gts - series and factory of assembly (Dubnica nad Vahom)
the cartridge case is not czech made, I think it is soviet import before czechoslovakia started its own production.

the disc is a powder cover

primer screw is KV-5-U - it is a correct one, I would expect czech made.

It should go with 57 OSv or ONhSv projectile - czech made

Out of curiosity why do you think it is Soviet import? Is there something on it to point you in that direction?

Hi Joe, the base stamps of Czechoslovak cases have different markings.
