Had a chat with the old chap who build this. he held the world record (with a sidecar) in the early 70s. Told him where we were from, and he said, ''do you know x, I got this blower off his brother''.. my mate said, yep, he's my brother, and you bought that blower off me about 15 years ago.. small world ..
Prices were in bubble territory .. £7500 for a Z1 restoration project.. yikes!
