71-80 (Excluding the ultra-rare stratosphere level of Rene' or Singer, etc..)

Any bike built w/ a Shimano "333" 3 speed hub or "FFS" crankset up front
J.C. Penneys 10 speed delux
Free Spirit
Murray
Big K
Honorable mention to Roadmaster....

But if I couldn't find those, these are all realistic:
Gitane TdF or Super Corsa
Several of the Schwinn Paramount models
Peugeot PX-10 or several of the Follis models
Any of the pre-80 Trek's w/ Columbus or Reynolds
Raleigh- several of the Reynolds 531 models
Honorable mention and most underated: Several of the Motobecane models, Grand Record and Grand Touring

And I didn't even get to Italy.....which would be a big list....
This is really an infinite discussion
