Latch works.

has the engraved Czech words (see pic.2), some of them are first names, some are spell out for letter (if no such name, beginning with that letter), used for the military phonetic alphabet .
On the inside of the lid is engraving
"POZOR, NEPRITEL NASLOUCHA! "
,which in exactly translation
" BEWARE,THE ENEMY IS LISTENING"
....... every signalman must obey...... good example of Cold War paranoia.)))))))
There is also engraved diagram on right side in the lid how to connect phone with wires (see pic.9,11).
Weight 7.10 lb.
Dimensions 10"X7"X4"
I don't have second phone to connect to for test, so I tested it in way as I can.
When I connected DC source to contacts inside battery compartment and pressed pushbutton on phone handle, phone ringed.
When I inserted crank lever and rotated it I got some voltage on phone line contacts, generator/dynamo works (see pic. 12).
I don't know how to test microphone and speaker in phone handle.
I found very interesting video on YouTube about this model of field phone, you can take a look on it, it is exactly same as I am selling,
NOT MINE
