The reflectors and decals lead me to think later '70s, like '77 or so. We should probably wait for the date on the hub.
And there is what started my inquiry into help with the date............ the hub is not stamped.
The guy I bought it from thought maybe '71 ........... he was not sure. At any rate it is finished and I rode it this morning for it's maiden ride. I will try and get some pics this afternoon and post them up.
