This set consists of a pair of accurately shaped, thin, distortion-free, vac-form sliding hoods to model an open canopy for your Spitfires. If you want to display your Spitfire with the canopy slid back, a vac hood will dramatically improve the look, as kit canopies are thick and will not fit over the spine unless they are molded larger, which looks odd. This set is applicable to all marks of high back Spitfire, from the later Mk Is through the Spitfire Mk 21, for any 1:72 Spitfire kit.
