Denver,
That is definitely a UO8 of the '68-70 vintage or so. I have a '68 or '69 that my wife rode through college. It is really a nice riding bike. I've done the Hotter-N-Hell 100 on it in Witchita Falls and lots of tri's, including the Red Man 1/2 Iron Man in 2007.
Many of the plastic-ish Simplex deraileurs bit the dust, but mine still works fine. I have squeezed a 7-speed cog set in the back with no problem.
Expect it to weigh about 28 lbs or so.
Ditch the current seat for a period Ideal leather saddle and someone might pay up to $250 for it, depending if whether they had one before. I know of several that have gone for that much, but that would be top dollar. PX-10's of the same era are nice and start in the $500.00 range.
Best single change is modern alloy wheels that weigh literally pounds less than stock.
Ride it and enjoy it.
