I wouldn't say they didn't survive past 1965. I had one in 67/68, but I only really wore it when I was planning to get a ride on the back of someone's scooter. Many scooter boys in N W England wore them at that time. Scooter boys in S E London wore them when I was down there in 68/69, though the hard-core, non-mod scooterists wore Belstaffs. What died out amongst 'hard mods' -> skinheads in S E London was the use of scooters at all.
