Marco Bonfanti was the owner and key person behind the Italian company C4.
NJC stands for No Joint Construction.

I think the offered frame at ebay has a pretty bad paint job, it's a bit of an overkill...

Looks like my old catalogue...

Have one...For sale at the right price (make an offer), the bike is now equipped with full M730 instead: Black M730 cranks w. black M730 chainrings, black M730 chainringsbolts, black 732 brakes, levers and pods. A painted black fillet brazed handlebar/stem combo follows (might be a Ritchey) Volare SLX saddle in black. Nos m730 cassette follows. I will post it later on Retrobike when I have time to shoot some nice pics.
