 On frontline . The set is developped in 1944 by Staru in Stassfurt , it’s a big factory 

producing civilian sets , and military  like feldfu , fusprech , klein fu set d, also

a special receiver for the fritz X . No technical notice is knowed , serial number is 35 

not a lot were made . freq pruf f is used on frontline for quick check of frequency, but when a fauly feldfu can’t be repaired , they send it to workshop  where they measure , modulation , selectivity  ,voltages , with the help of this wonderfull set

The former French owner of this set , had let it works on some functions, he removes

Super rare test device.   I also collect test devices as they are beautifully made and have great parameters even for today's standards.
