I have a forty-hole hi-flange Campagnolo rear track hub laced to a Mavic Record du Monde De L'Heure 700 cm tubular wheel. It comes with track nuts (I am not sure whether the nuts are Campagnolo or not) and a 14-tooth cog, no lockring. The spokes are stainless and I think they are Wheelsmith (I can't quite make out the marking on the end). If I remember correctly, the hub is from 73; it is from the seventies. The wheel is in excellent condition: spins smoothly, no rust, spokes are excellent, and the rim shines.
$135.00 plus mailing within the USA, around $20-35.
I have pictures that I can send if you want.
