A friend asked if I could help identify a frame he has. According to him, the frame was originally decaled as a Leoni, and it had some "Leoni" pantagraphed parts. I do not know if the "spade" cutout lugs are proprietary to Colnago, but this has the bottom bracket spade lug and the "spade" in the headtube lug. It has Campagnolo drop-outs and Italian threading. You can see pictures of it at the following:

Thanks for the help.
