Just yesterday found a '74 LeTour in opaque blue at my local thrift for $10. It's 60cm, Sun Tour XV derailleurs, Aluminum Sunshine hi-flange hubs, chromed steel rims. The paint is in pretty rough shape. I've got it stripped down to the frame and have started cleanup. I'm going to update the wheels to cut a little of the weight and commute on her this winter. Should be a fun project. Keep hitting the thrift, yours will come. Good luck.
