Metal box with hinged lid containing Morse code equipment – batteries, bell, transmission key. Remains of webbing carry straps on back (see photo). This item has been modified from the original design. The item has a battery box located behind the Morse key but the original battery has been replaced by two rectangular 1.5 V batteries which were placed in the shelf below the Morse key. That shelf was initially intended to store the audio telephone hand piece which is no longer with the device. Hence, the final use of the item was as a Morse key only.Stencilled on outside lid (see photo): TELE SET D M (3 or 4 other indecipherable faint letters/numbers; likely "D. MK V." with star) YA. 6371 Inside (on movable frame, for holding hand piece): PRESS KEY WHEN FINISHED Stamped into metal lid of battery box (behind Morse key): PX SERIAL NO. (no actual serial no. stamped on lid)
