I just completed a Ferrari 250 GTO using an Italeri model kit. The chassis is Ulrich. A brass guide mount was made to replace the missing chassis part. The car is powered with a Pittman DC77 6 volt motor.
The used Russkit wire wheels were cleaned up, and Paul's tires are used. The bevel gears are Tradeship.
I covered details of the Cobra previously. The chassis is a hybrid Ulrich/Dynamic, and the car is 36D-powered. The body is Monogram. Wheels are Revell.
