Compact green leatherette case with metal clasp closure, rectangular shape with rounded flap edge. The case opens to reveal a series of small electrical components — including cylindrical connectors, plugs, and possibly miniature tube sockets — all neatly arranged within a light felt-lined interior compartment.
A metal ring fitting on top suggests it could be secured or suspended within a larger Telefunken equipment case or field unit. The interior photo indicates the case was designed specifically for organized component transport, ensuring electrical accessories were protected and readily available for maintenance or calibration of Telefunken communications equipment such as the PE-484 field radio system.
