Just picked this up today, I haven't had a chance to look up build date. I'm guessing late 70's early 80's, serial number is under the headbadge. The paint is in decent shape, a few nicks and scratches. Has a cool Duro whitewall cheater slick, I wish it had the correct sting-ray seat, might be a future purchase. As for now just a simple afternoon of cleaning and it's ready to ride.
