For the WSC60s Ford GT40 Mk1.
Essex Wire, alongside Ford France, was among the most successful privately ran "works" team who ran GT40 production chassis during the 1966 WSC season.
At the 1966 Nürburgring 1000km, two cars were entered for Essex Wire, neither finished. P/1026 (#46) driven by Skip Scott and Peter Revson dropped out with an oil leak. Funny how the sticker people at the Ring sometimes added a load of extra racing numbers on the cars. Its not even consistent!
