My question is if your frame is French tubing with French threading. Can you determine the tubing type and measure the steerer for both length and diameter? Can you post a picture of the Reynolds 531 decal?
Sorry for the long delay - I needed a good time to get greasy and fussy. The thread on the steering tube is 1mm pitch, on 25mm OD, 22.2mm ID, but the headset is stamped 1 X 24. This explains the stripped threads. The steering tube is 8 7/8" long, and the fork offset is about 2". The 531 decals are under paint. A scrounged fork would really be in character for saving my faithful old friend. I even had a roommate who imported a really good Trek in '84.
