Up for sale is an original, genuine vintage British Royal Air Force (RAF) teardrop fuselage navigation lamp assembly. Stamped with the official Air Ministry vocabulary stores reference number 5CX/5315, this clear-lens external aircraft illumination lamp is a Thorn Type FNL.50 standard layout. It was heavily integrated into iconic post-war and Cold War British military fleets, most notably serving as a primary structural navigation light on the English Electric Canberra jet bomber and various Gloster Meteor variants.

This particular example is a pristine New Old Stock (NOS) item, remaining completely unissued, unmounted, and preserved inside its original military cardboard storage box. It is an ideal find for active vintage warbird restorations, aircraft museum archive displays, or collectors of high-grade British militaria and aeronautica.
