Pastor Bob,
Your keenly calibrated eye is right on the money. She currently has a Campagnolo Rally long cage and freewheel to match. And yes, those are Schwinn Approved "indexed" shifters. I do have the original Campagnolo Record rear derailleur and Regina Gran Sport Corse freewheel along with the original Campagnolo friction shifters. My intention is to put her back to original specs. The hoops are Weinmann and I think they are original. Take a peek at the image that Scooper posted of the '69 P13 spec sheet.
