So I'm building a bike to use when I'm at home in LA (most of my time is spent in Boston) and I've been looking through craigslist and some local bike forums. The other night an ad caught my eye for a Guerciotti track frame. I've been trying to build a fixed gear and this caught my eye because it was in my size. I got in contact with the seller and the next day he sent me photos. It'd been repainted with a sort of lace pattern, quite unique. Because of this, all the original decals were gone. The top of the tubes that connect the rear triangle to the seatpost (pardon my lack of bike terminology, the proper term is escaping me at the moment) are pantographed "Guerciotti", and the crown on the fork is pantographed with the Guerciotti "G" logo. The lug connecting the downtube to the headtube also has the typical star cut out of it. It has Campagnolo dropouts. My confusion though comes from the bottom of the bottom bracket shell, which is stamped with the Cinelli logo. Is this some sort of frankenstein italian bike or did Guerciotti just use Cinelli lugs or is there some other explanation? There's also another logo that I don't recognize, resembling a sort of handprint, on the horizontal bar where the rear brake would go on a road bike. I went and picked up the frame, it's in beautiful shape and I"m looking forward to building it up, regardless of who made it. I'm just curious about the history of this frame.

Here are the pictures the seller sent me, I'll try to take some better ones later.
