Marcus,

I have one from my mid-line (531 db main tubes) Falcon purchased around 1968 or 69. I upgraded it to a Nuovo Record and added Zeus crank, then the bike got stolen. The derailleur is nearly complete. I think I cannibalized the idler wheels for a brass Record, but I do have the original wheels.

We can compare parts if you'd like, seein' how you're local.
