FF33 1938 (no green stripe)

[kabel]

I have got one of these early telephones with no green stripe, and the typical early circuit diagram.

The phone has been used in the Norwegian forces until approx 1970.
Microphone (transmitter capsule dated 73)

The phonetic alphabet is NATO and the circuit diagram is only a blank plate.

Is it special or rare? I have 8 others, all with the green stripe circuit.

Hi kabel,
usually the early types were changed to be in accordance with the new, separated concept (capacitors and plates as well). Still a good percentage (maybe 25%) remained untouched. Your piece is probably a Norwegian NATO reissue, not often seen, so keep it as a technical timepiece. Some photos would be nice to see.
I will soon recieve an OB43 as a NATO reissue

Too bad that there's no original microphone without "green cross" on it. This microphone is quite a rare stuff...

Some pictures, just as it came out from 45 years of storage with no maintenance:

The grey plastic battery box looks "new"
