By Siemens. Size 57. Manufactured in a flecked brown reed linen cloth with a green satin lining and lambswool inner 'earpieces'. This example has the usual brown leather covered earphones and is fitted with hooks/strap for the three-strap oxygen masks. Fully wired with LHB 1 (Mi 4a) magnetic throat microphones, loom and four-pole break coupling. It also fitted with receivers and plastic soundboards. The cloth is in excellent clean condition bar a tiny repair to the front edge forehead area. All straps and buckles are very good although the metal components do have minor surface corrosion. The lining is equally good and complete with nice labels and stamps. Excellent avionics. A really good example. Stock code H16160.
