WOW! That frame looks like it would flex until sometime in the next century!! Are those things pedals, or some kind of prop to hold it up at shows?? After you mentioned Captain America, whom I remember racing when I started in '76, I didn't have just the rear flip/flop, I had a hub SET. The front was not much bigger than an axle, and it had a nut and bolt arrangement to fix it to the fork, NOT a QR. After about a week, I put a QR in it. I tried a Campy, but the hole was too small, so I put in a Maillard. That bike does NOT look raceworthy. I remember the first Trek aluminum bikes were glued and pinned, and they were flexy flyers as well. I also remember EXXon Graftek but together a Carbon Fiber bike,that wasn't as good as the current ones, but definitly better than the auminum bikes of that era. I wonder what the racing bikes will look like a hundredyears from now? Plastic??? Probably not bamboo, because there won't be any then. LOL.
