Shell case marking KWK, info needed

[spitfire22569]

Hello,

I'm recently learning about the KWK cannons used by the Germans.
Here is the list of KWK guns (source: Wikipedia)
2 cm KwK 30 L/55 110 cm PzKpfw II
2 cm KwK 38 PzKpfw II
3.7 cm KwK 36 L/45 166.5 cm PzKpfw III, Ausf. A-F
5 cm KwK 38 L/42 210 cm PzKpfw III, Ausf. F-H
5 cm KwK 39 L/60 300 cm PzKpfw III, Ausf. J-M
7.5 cm KwK 37 L/24 176.65 cm PzKpfw III, Ausf. N, PzKpfw IV, Ausf. A-F
7.5 cm KwK 40 L/43 347.3 cm PzKpfw IV, Ausf. G
L/48 385.5 cm PzKpfw IV, Ausf. G-J
7.5 cm KwK 42 L/70 525 cm Panther, Panther II
8,8 cm KwK 36 L/56 492.8 cm Tiger I
8.8 cm KwK 43 L/71 628 cm Tiger II

Now, my question is as follows: Did the produce special rounds for these guns, stamped with KWK marking or not?
For example: I know the KWK 40 had KWK40 stamped on the shell case.
Was this also the case with the 2cm and 3,7 cm or did they use Flak or Pak casings?
I have the same question with the other guns.
Like the KWK39, was it stamped with KWK39 or with Pak38?

Thank you in advance

No, not all the cases would be stamped with the kind of case it was. Some (2cm used same case for Flak and KwK) would have maker's stamp, lot batch, year and WaA. Others would also have a code number for the kind of casing: 6331 for 3,7cm Pak casing, 6348 for 3,7cm FlaK casing etc. And finally the largest would also say for what type of gun it was made for: Kwk40, Kwk 42, Kwk43 etc. Some early large cases wouldn't have the kind of gun but the kind of case code only.


I don't know all the variations but they can be found around the internet.
