Thanks, it was a Craigslist find. I've since replaced the generic dyno lights with an authentic Schwinn approved Union set, everything on it is correct for 1974 exce the computer.
Amazingly I get compliments on it almost every time I ride it, and mostly from folks on high end bikes.

I know ef Schwinn's are usually considered to be boat anchors, but I find it to be a pleasure to ride.
