Does anyone know who built the KHS John Howard Professionl frames. I have one and I don't believe it was actually made by KHS. The bike is Columbus SL with campy drops and a Cinelli bb. Fork has an internally lugged fork crown and the brake bridge is angled up to the center. The chain and seat stays are very nicely finished. No serial numbers, only a hand stamped KHS on the top of the non-drive side of the bb. I'm guessing the vintage is around 87, since Dave Tesch made them up to 86.
