Is there any evidence that they were used against German armored vehicles in 1939? I suppose they were of conventional design with steel core?

There must have been an error in source, because now I read in other books, that PS should be APT round, not API. Anyway, P bullet was an equivalent of German WW1 steel core SmK, and APT was its modification.

In case of infantry wz.30 HMG, for 2000 rounds there should be 1766 ordinary SC, 200 P (AP) and 34 PS (APT). I have no idea how they were belted. Unfortunately, I haven't found information how common they were in armoured vehicles. I may assume, that more common, than in infantry.

I have no data as for armour penetration, but it should be no more, than some 8-9 mm - enough for own tankette, but not enough for PzKpfw I...
