I'd like to know if anybody has come across a De Rosa like this. Here is what I know of it. The fork and frame is steel, no sticker to identify what kind, the fork has smooth crown with De Rosa and heart pantograph; the front lower lug has heart pantograph and it is elongated; the brake bridge has De rosa pantograph; bottom bracket is Italian thread with heart cut out at the bottom; rear spacing is for 6 or 7 speed, I tried to fit 8 speed wheelset but will not fit; the drop outs are campagnolo; there is no front dérailleur hanger and the cable is internally routed. Here are pics of the frame and fork.
