Antique motorcycle. 1929- 1938 - $7,000 (Marana)

Original, semi complete motorcycle.
1929 - 1939.
Thought to be Indian but we don't know for sure.
Cannot find a similar example.
Parallel twin engine and tranny were built specifically for this frame so it could be a prototype racer.
Nothing has been altered or cut on this bike.
Speedometer housing cast into frame so it had a split tank at one time.
I was going to refit it with modern engine and use original transmission but too many projects already.
Dad owned it for 45 years and Ive had it 7 years.
Non clincher type 17" tires.
Tranny and clutch seems to work fine.
Great project with original forks, engine, wheels and tranny.
Asking $8,000.
Research and complete it or modify with modern engine.
In Marana,Az.
Text or email prefered as I am almost deaf.
