Also having problems dating the frame and have had no luck getting back answers from Waterford or Schwinn... Series PDG.
Going from RX100 to 7-speed Dura-Ace would be a
downgrade not an upgrade. RX100 was much newer than 7-speed Dura-Ace.
In general, you want to avoid
any pre-9-speed Dura-Ace stuff, because it's an orphaned line. Generally inferior to the newer stuff even at lower price points, and with various interchangeability issues.
If you want more details about old Dura-Ace, see:

The PDG frames, I believe, were Japanese, and neither Waterford nor the current owners of the Schwinn brand name had anything to do with them.
