Mike et al,
Thanks for pointing-out the RH...it didn't seem to go outrageously high but then values are relative. Of interest to me were the brake calipers that appear to be centerpulls installed on cantilever-like studs. Interesting choice...esp when bike is supposedly a "racer". Also, the roller brake actuation...similar to some DC 510's (centerpulIs) I have that came on an early-80's Trek 720 (before the later cantilevers).
And yes, very interesting if truly chrome-plated 753. That's pretty thin stuff to begin with and weaker still after the corrosive plating treatment.
