Rectangular metal case with a clip latch and painted stencil markings “ZA-1904” and “19” on the exterior. The interior lid features a printed paper label titled “Case Spare Parts No. 5C – Contents”, listing component names and corresponding RCA or ZA part numbers.
Inside the box are various electrical components, including small connectors, bulbs, resistors, wiring, and other radio-related hardware. A small cloth pouch holds additional parts. Several items are labeled with military-style part codes (e.g., “RCA,” “ZA,” “P.V. 30476”).
This case would have been used as a field repair kit for maintaining military communication equipment, likely for a Wireless Set No. 19 or similar radio unit used by Allied forces during the Second World War.
