Dockjock, check with a guy who posts as Lame over on pprune and Airdisaster. He has a sh!tload of memorabilia stuff, some of it from PanAm, that he was selling on e-bay.
On another note, the first sim instructor I had at Allegheny Airlines on the 227 was an ex-PanAm guy named Raoul Munoz. He''d started with them back in the 1930''s and had flown the Boeing 314. Knew Fred Noonan and Ed Musick.
