Czechoslovak/Yugoslav Partizan docs.

[Al-muell]

I wasn't sure where to post it - in Yugoslavia or Czechoslovakia section, as the owner was a partisan in Yugoslavia, but on the other hand, he was Czech by nationality, member of Czechoslovak unit and judging from the second doc - he returned to Czechoslovakia after the war.
So, here it is, a group of two docs and a photograph(Yugoslav Partisan ID dated 1944, Czechoslovak partisan movement member ID dated 1946 and an additional picture of the owner).
It is to kapetan Jan Janec'ek (funny name - sounds like "John Johnny" to me), partisan and health (or veterinary, if I read the serbo-croatian properly) referent of the Żiżka Czechoslovak Partisan Brigade in Yugoslavia. Interestingly, it seems that he didn't get Czechoslovak partisan badno badge number is given.
Anyway, If anyone can give me some details on the Brigade, or at least tell me where I can find some? Sources may be in Czech, if nothing else is available.
