This extremely rare model was issued in 1968 and used the box of the 1966 model with added sticker and a new stock number. The rare car shares the Harrison “duck tail” body with Pactra, that also issued it as a kit and a ready to race model. While the Pactra is not especially rare, the one issued by Testor is very scarce, and this one has the only box known to exist at this time.
The chassis is different from the earlier issue and uses a steel wire form for drop arm. The Igarashi “MK3” motor has a zinc die-cast endbell with Pittman-style brushes.
