Putting together my knowledge of that time period (and a quick google search), leads me to believe this is one of Connie Carpenter's former bikes from the early 80s. The PO also said that he'd gotten it from a seller in Colorado this year, further linking it.
Then there's this article from this spring about Eisentraut having built a frame for her during the same time period. Some of the details don't match, but it was still obviously done by a "builder of quality", as the saying goes.
Nice bike. I concur it's probably a custom build re-badged as a Puch for sponsorship reasons.
Cinelli SC bb shell, stamped "Carpenter"
This style Cinelli BB shell was made before about 1981. The later shells had the "winged C" logo instead. Of course, the shell could have been old stock and built into the frame at any time.
Looks like Campagnolo BMX hubs. I don't see a lockring on the sprocket.
