Thornton-pickardmfg. Co. Mark III Hythe Camera (MK III H) (Aerial)

The Thornton-Pickard Mark III Hythe Camera (MK III H) is a British aerial gun camera built in the shape of a Lewis machine gun, used during the First World War to train aircrew in aerial gunnery without live ammunition. Pulling the trigger exposed a frame of film, allowing instructors to assess a trainee's aim against enemy aircraft.

At UK auction, hammer prices for the Mark III Hythe have ranged widely — from £120 at saleroom level in 2000 up to about £2,000 in 2021, with a more recent 2022 result around £560. As of today in 2026 the small sample size means what a Mark III Hythe is worth depends heavily on completeness, originality of the wooden stock and metalwork, and provenance, with militaria-grade examples sitting at the upper end of the range.
