Mark,
I have some information that I have been compiling on Max Franzisket, thogh not yet complete. See link to my website below;

It would also be useful for you to get a copy of Eric Mombeek's "Eismeerjager Band 1" which cronicles the Zerostorerstaffel of JG5 which Franzisket was a key member.
Cheers
Jeremy
