1920-1945 Dutch Aircraft mechanics bullion trade badge ?

Pre-WWII Dutch Naval Aviation Bullion Badge – Aircraft Mechanic / Technical Branch (Unconfirmed)

A gold bullion speciality badge on black wool cloth, believed to be pre-Second World War and associated with early Dutch Naval Aviation Service (MLD – Marine Luchtvaartdienst) personnel.

The central motif features a gold bullion propeller over a stylised radial aircraft engine, surmounted by a continental-style royal crown closely resembling the Dutch Rijkskroon used on Netherlands military insignia. The combination strongly suggests an aviation technical or mechanical trade within the Koninklijke Marine during the interwar years (c. 1920s–1930s).

While the exact pattern has not yet been definitively matched in reference sources, the construction, materials, and iconography align with early Dutch naval aviation specialty emblems, likely worn by:

• Aircraft mechanics

• Engine fitters

• Technical branch personnel

• Or early MLD aircrew support staff

The badge is hand-stitched in high-quality gold bullion wire on a black wool backing, with an early coarse linen reverse — a construction style consistent with pre-WWII manufacture
