The famous “Project 34”, known simply as six-wheeler, was revolutionary design by Derek Gardner. The car used four specially manufactured 10-inch diameter (254 mm) wheels and tyres at the front, with two ordinary-sized wheels at the back. Both Jody Scheckter and Patrick Depailler produced good results with the car, but while Depailler praised the car continually, Scheckter was unimpressed. For the 1977 season Scheckter was replaced by Ronnie Peterson, and the P34 was redesigned for cleaner aerodynamics, and some redesign was done on Peterson’s car to accommodate his height. Peterson tried the six-wheeler first time in November 1976 in test session held at Silverstone. It was 1976 specification car in old all-blue livery. The rare old model made by Twin Crono, which is slightly smaller than 1/43, represents 1976 P34 by Peterson.
