Although according to Dennis Jenkinson's book "Historic Racing Cars" the uncompleted GP4 machine was converted and became F2/3 this was not correct and chassis GP4 was sold to Bobbie Baird in Ireland and eventually became a Jaguar engined 2 seater sportscar. It competed in this form and still exists as a Jaguar 2 seater sportscar. F2/3 was no more successful than its siblings. F2/4 followed in construction and was sold to Orlando Simpson before Peter Whitehead placed an order for what was to become the last Alta car built: F2/5. This F2 Alta was entered for World Championship Grands Prix events, first driven by himself in the 1952 French Grand Prix, and then by his half-brother Graham Whitehead at the 1952 British Grand Prix. Neither run produced a points finish, but this was not to be the last time that the Alta name appeared in Formula One.
