Well it would be if Mr Elioti would at least give a clue as to who his Dad is....
My dad used to race bikes proffesionaly, and had a garage and test bench with a famous singer. This engine was run up, but had an issue with the oil pump, he gave to someone to rectify, and they lost parts, so he gave up on it for 40 years. I've seen a newspaper article on it from years ago , not the same engine as the peck special, but from the same moulds / castings. Will get more pics, and a video as due to be fired up any day soon:)
