Wehrmacht Sanitätstasche - Trying to find info about owner

[Von Thronstahl]

I´ve bought this Sanitätstasche  recently. Inside the bag I´ve found name of the owner and Feldpost number.  Owner is Dr. Frimmel and Feldpost number is 42595.

Sanitätstasche  was produced in 1943 and I have found that 42595 was Feldpost number of 2. Sanitats-Kompanie 44. (12.3.1943-7.9.1943). 

This is where my knowledge stops.  Is it possible to find out more about Dr. Frimmel using available info?

I bought it in Croatia. I think it was never in collection before. I need to ask the seller additional info about it.  Searching through WH Lexikon didn´t help or I am doing something wrong. I presumed that he was stationed  somewhere in ex-Yugoslavia but all the units I found that had this 2. Sanitats-Kompanie 44 attached were not in this area.
