Original Wehrmacht Dfh.f. headset usually used with the various field radios. Marked bmm 41. This one is missing the cord and the springs for the cord are rusty and broken. An ideal set to repair, as the head band and ear pieces are actually fairly nice, so you could install new speakers and re-cord them. This is an actual military headset, not a civilian pattern. I did not test them because it looks like they probably don't work and the wires are too far gone to even try without tearing into them.
