ammo holder Kal. 4 for a german tank (?)

[SSG]

Hi there,
once again a question:
I got a new item in my collection, it should be an ammo-holder for Kal. 4 cartridges,
which is used in a german tank, but the seller doesn`t know, if it`s the HS 30, M 113 or Luchs or Hotchkiss....
Can anybody tell me, out of which "tank" this part comes??
Thank you very much in advance!
SSG
