Resurrecting this topic, there is a full chrome 1975 short-coupled (Sprint style) Paramount P13 on eBay (not mine):
Schwinn Paramount Sprint Bicycle Road Bike Keith Kingbay 1 of 5 Campagnolo | eBay
It appears to be serial number F7506, which would make it the 6th frame built in June 1975.
Note that 1972 was technically the last year you could get a full-chrome Paramount, however the seller appears to be the grandson of noted
Schwinn executive Keith Kingbay, and I have little doubt that this could have been an executive order chrome job.
While many of the original components have been replaced, this is definitely a rare and noteworthy bike!
