To help out on the dating, here's the one I had for a couple of years, definitely Bike Boom era (73-74), wheels and derailleurs are not original. While definitely the bottom of the line bike (no chrome on the lugs, nothing special about the tubing), it was a damn nice rider. Unfortunately, one frame size too large for me to really get comfortable, ended up selling off the frame, most of the rest of the parts had been put aside in the hopes I'd find a 56/58 frame, but they ended up lost in the fire.
