She was a spare parts special all right. The rear cover was a modified 753 (F3) one, the oil tank mounted on part of the old style 742 (F2) "Monster Bracket" while the single pole rear wing was from Ron Dennis' Project 4 parts bin. The cockpit and nose were 761 (F1) made from a mould I flopped over some film cars John and I were involved with.

After much research by the guys at oldracingcars.com it appears the tub started life as a Brian Henton 732 F2 car which he crashed in 1973 (again) and sent back to March to exchange for a new one as part of their "swap-a-crate" scheme. March then rebuilt the tub and re-plated it as 742-U1, the pre production mule.

John bought it via Dave Price Racing from Val Muscetti who had run it in F/ Atlantic, ShellSport etc in the UK with a variety of engines. Practically a new car!
