- Steerer tube was stamed Reynolds 531
- No other dents
- Got some better pics of the serial number

Bad News (from least to worst):
- Few more scratches, paint bubbles and spidering (not too bad)
- Slight bend in left seat stay (minor, I've straightend worse bends)
- Crack in paint and possibily brazing around left seat stay/brake bridge (doesn't go all the way around)
- Incorrect bolt used for seat tube clamp...different threading, so stripped original threads
Pictures below...
The bolt that was in there to left compared to a proper bolt from another bike upper right.
Reviving an old thread because I'm trying to rescue a ratty '81 710 frame, and I've just pulled EXACTLY the same bolt out of the seat binder.
None of my SAE or Metric allen keys will fit -- it's somewhere around a 4.5mm -- and the odd thing, relative to John's long-ago comment above, is that a standard M6 head definitely does not fit into the binder receptacle. So a regular M6 surely can't have been the normal bolt for this, even if this weird black thing is also wrong.
anyone with any clues?
