The Napier Lion VII D was  installed in the Gloster VI N250 Schneider Trophy float plane in 1929. All parts were made by hand as masters, then moulds made from them. The parts were then reproduced in cast resin. This was necessary as besides this aircraft replica, two further engines are required for a future model of the Railton Mobil Special LSR car of John Cobb.

00-90 brass nuts and bolts were cut down into studs and nuts, then plated before installing. 308 studs and nuts were required to complete the model. The levers at the rear of the supercharger were a bit of a pig to make as they were carved from aluminum sheet.
