Well maybe I was mistaken in identifying mine as a UO8, but after I researched it thats what I concluded. It was my first vintage so I was a bit ignorant and I admit I could have made a mistake. Here is a link to my Flickr with pics of the bike now as my campus beater. In person it clearly says "Reynolds 531 Butted" but it was hard to get a good picture of it. There is only one pic of it how it was when I got it, and its pretty poor quality.
