I have made a mistake and the threads on the fork are english.I pulled the bike apart and the fork steerer says reynolds 531 butted on it.I found up inside the fork a plastic bag that was rolled up neatly and had a receipt from the bike store it was bought!It has that it was custom made for a lady in daytona beach christmas 1978 with phone number etc?it was bought at Seebreeze bike shop in daytona beach,anybody know if they were a Raysport dealer?
