Dieselpunk Headphones

These are some probably war-time headphones, Omega "Typ 5T" brand, with Koss PortaPro speakers modded into them. I do have great respect for old stuff, so all the old parts were unharmed and put into bags respectively for left and right headphone. The only thing that were damaged were the portapros. The box only contained the headphones, and "Typ 5T" is the only text on the box other than "OMEGA".
