I remember a set of Phillips 'Philite' rubber tread pedals being on one of my father's bikes for many years. There's a slim chance that they could be in a box or drawer in his garage but I doubt it. I think the 'cats eye' type reflectors in those pictured are custom as I don't recall anything...
Nothing wrong with the M71, I used to ride them a lot for time trials, especially on fixed wheel. I now regret that when I stopped racing I sold my pairs.
I've seen some 40th anniversary pedals, they were early Look clipless design in black & white with Colnago 40th Anniversary branding on the back. At the time I was still using clips & straps so didn't by them.
Colnago Master with a Record chainset and matching 102 BB. With the chain on the inner ring (39t) and smallest sprocket (13t) I get an occasional rub on the outer ring pins - nothing else. If it wasn't against 50 years of habit I'd be happy to ride 39/13.
That's because Sean started life as a tester - and nothing wrong with that, that's how he got his TdF stage win. Even his cyclo-cross bike had horizontal brake hoods.
Chain/sprocket clearance. I had a frame back in the 70s (a MKM if I recall correctly) which was fine with a 5-speed block but a 6-speed would jam on the end of the chainstay when swapping wheels. I had the stay end filed back and filled with brass.
That's an early model Laprade seat pin. If you've never seen one before you may be surprised when you discover how long it is compared to others from the same era (late 70s/early 80s). Hopefully it's not stuck because there's a lot of it.
