Hello everyone,
Many thanks for all the replies.
Cinco, I put the fork it came with on, doesn't look too bad to me (see photo).
Bianchigirll: Head tube angle is about 70°; the fork seems about the same. Wheelbase is 100cm.
Sokito: Only visible damage to the headtube is the chip in the paint. I can't see any bulges in the headtube.
I was bothered about the cracks in the top and down tube paint because of the various horror stories about this. Seems hard to judge:
some people freak out about damage that looks much less serious, while others would contemplate fixing things that look much worse to
me.
Gary: The Alan has an aluminium fork. Does this help date the bike, do you know? I've only taken it for a very short ride, but I like it so far.
Anyway, thanks again,
John
