Ed,
The base kit is the 50 year old AMT Parnelli Jones 1963 Watson Roadster. It however has been heavily modified to correct the issues with the original kit (resin replacement nose and resin replacement tires from Indycals, Vacuumed windshield, Aluminum rod ends, Aluminum exhaust pipe, etc.. etc..) I have a fully detailed photo album of the build on my facebook page
