Hello I bought an Indian Enfield which had been converted to a dirt bike and was missing all of its original body parts. I have been informed that it is a '55 500CC twin engine in a 1956 frame, and was probably an Indian Tomahawk. The engine number is 5T4775 and the frame number is 11173. Can anyone positively date this bike? I have also attached a picture as it was received, I have since removed the Yamaha front end and dispatched it to junkyard hell. Thanks,
