lovely odd shape on the bates there. It kind of looks like the shape complementing function or something like that... maybe a small spring effect?
Like Hetchins' curly stays and Baines Flying Gates, Bates Diadrant forks were really all about letting people know you had a Bates, and nothing to do with function. In the olden days, amateur riders weren't even allowed to have the frame maker's name on the bike just in case they were being paid to ride a particular brand, so manufacturers came up with distinctive designs which would be recognisable even on stealth bikes.
