75mm KwK 38 question

[earni74]

AS YOU CAN SEE ON THE PICTURE, I HAVE A 75MM KwK 38 CASE ON THE LEFT, THE NEXT 2 ARE APCBC-HE, THE 1 PIECE HE PROJECTILE WITH FUZE KI AZ23 umg AND NEXT IS A 2 PIECE PROJECTILE WITH FUZE AZ 23, THE LAST ONE IS A ( DEUT ) MARKER PROJECTILE ( BASE EJECTION ) WITH FUZE Dopp ZS/60s.


MY QUESTION IS, ARE ALL THESE PROJECTILES FOR THE KwK 38, THE 2 HE PROJECTILES ARE THE SAME HEIGHT AND THE CRIMP GROOVE ARE THE SAME DISTANCE FROM THE BASE OF THE ROTATING BAND.


THE 2 APCBC-HE PROJECTILES ARE NEAR IDENTICAL AS IS THE CRIMP GROOVE.


THE MARKER PROJECTILE IS THE SAME HEIGHT AS THE HE PROJECTILES AND THE CRIMP GROOVE IS THE SAME AS THE OTHER 4 PROJECTILES.


I HAVE NO INFORMATION ON THIS PARTICULAR ROUND OF AMMUNITION, THE CASE CAME WITH THE FUZED K1 AZ23umg PROJECTILE, IS THERE A WAY OF IDENTIFYING EACH PROJECTILE SPECIFICALLY, THE BRASS WASHED STEEL CASE HAS HEADSTAMPS 6354St 7.5 KwK 1939 WAFF STAMP & P


THANKYOU

Hi,
there are different sources You can use. Some give different answers. I try to make a short summary. Anyone please feel free to correct me.

White tip on AP projectiles is a designation for 7,62cm rounds so they do not belong in the KwK case.
The 7,5cm Gr 34 (fuzed with kl AZ 23 umg) is possible, I would expect regular kl AZ 23 fuze.
Projectile with AZ 23 is K.Gr. rot used with the F.K.16 n.A. - does not belong to the case.
The Deut projectile is listed for KwK only in Merkbl.geh 28/1 Zusammenstellung der Explosifstoffgewichte... from 1944

As for guns designation the correct designation is 7,5cm Kw.K or Stu.G. 7,5cm K. possibly also 7,5cm K 37 (Sf)
