France 40 - Rare ER40 earphones

France 40 - Rare pair of ER40 radio earphones, complete with cable and plug. The wiring is in excellent condition, fabric-covered, with no fraying or cracks. Adjustable headbands with brown leather reinforcements; some minor oxidation on the sliders. There are two types of earphones for this model, one marked ERICSON. The pair we are offering was originally equipped with both types (or may be a period repair). Beautiful overall patina. This model is the standard one fitted to all French WW2 radios and is also ideal for complementing a cutaway anti-aircraft helmet.
