Builders of the largest canopies are the audience for Montex and Master sets in 1:24. At this size each canopy frame is several millimetres wide and hand-laid masking tape becomes a lottery, while a die-cut Montex template makes the job routine. Turned brass Master barrels then give the guns of a Hurricane or Mosquito the weight plastic cannot fake. Sets for the Bf 109K and Fw 190D are listed here too.
The masks in this listing are cut for specific mouldings from 1:24 aircraft model kits, so check the kit named in the set title before ordering. How the two halves of a set work together, and which other scales exist, is covered in Montex and Master sets for aircraft. If you also spray insignia and wheels, see the standalone 1:24 canopy masks.
