Late war three tone FF33 field telephone marked rsm 1944

Textbook and very interesting so-called three tone FF33 (Feldfernsprecher 33) field telephone. This example gets the three tone designation thanks to the textbook construction where the metal parts used are finished in three different colours: tan (yellow), black and blueish grey (Blaugrau) which is typical for 1944 dated examples where the FF33 first started to be made with tan coloured parts! The FF33 is nicely marked rsm 1944 which indicates production in 1944 by an unknown maker. It is also features a mark “ark” which is an abbreviation for Arktisch which indicates the field telephone is designed so it can be used arctic climates. Excellent and very interesting late war constructed FF33 which would be impossible to upgrade!

Note: The field phone appears to be in good shape and is complete with all the necessary parts to use it including the battery box which is mostly broken or missing. I have not opened or tested the field phone!
