My guess would be around 1973, but you could get a more accurate date from the rear hub shell. The saddle leather is toast. it can be replaced, but it will be costly. White is a fairly unusual color, most Sports of that era were black, coffee, or green. I am surprised that the chrome looks so clean (except the wheels). You'll drop some money into it to get it in riding condition; so I would buy it as a keeper, but you will lose money if you flip it. For sale, it is worth more in parts than as a whole bike.
