Two fieldphones by F. Reiner in München, on the left (1939 - #28470) with early, unpainted metal furnishings and on the right (1941 - #43902) the later ones with black paint.
Still working fine after well over 70
years, the earlier one has some interesting
markings on the bakelite case.
The "FEIND HÖRT MIT (+ some faded, smaller text just below)" painted on
the side is rather rare.

Little seems to have changed internally in the two years between production, as the war progressed less valuable materials would be used for certain components.
Taken out of the bakelite housing by removing the 2 mounting screws, the red circle around their holes indicate a original paintjob.
Scratched on top of the 1939's battery lid we find a marking of less official nature, "Arschloch Von Meyer"!
On this picture, inside we see the bells for it's ringtone and
2 sockets for the interconnection cables.
Note the drops of paint at the screws and typical old wire.

MaterialPrüfungs mark without a maker number but instead accompanied by
a 3
