One was a touring version, the other a mixte, but I can never remember which was which. They sold a cheaper version called the AO-8 which had non-QR wheels, cheaper rims and crank, same frame but with less chrome.

That was my new UO-8 in 1972 IIRC. (I'm a bit fuzzy about the date. It's been a while.) I upgraded it with alloy wheels, derailleurs, seatpost, crank, handlebar, pedals w/toe clips & straps. I still ride it.
