Moggers I'm with you on the decal - Don't Touch It! It really adds to the character of the bike (actually my favourite thing about it) and in my experience once you start peeling/messing with decals they never look the same. I've always been a fan of that era of Shimano 105, it looks great and shifts well. The Columbus decals look original to me. That plus the forged dropouts and decent lugs say nice bike to me. As to it's origins, I want to say Bianchi but somehow I can't see Bianchi doing a celeste-ish fade like that. It seems more like another company inspired by Bianchi. Could it be a Miele? I bought my friend a Miele badged as a Pinarello that was Columbus tubing and all 105, the only thing is the fork crown was different. Then I was thinking, what about Fiori? Japanese build with an Italian flavour, and I've seen several with colorful fades. This isn't a good example, but as good as I could get:

Anyway, if you want to try a fixie, that's great, but if I were you I'd keep this one stock and find a beater/hi-ten bike to turn into a fixie. I will keep thinking. Something about that white/celeste fade looks very familiar to me.
