I have a Continental of about that age. It has the 'Schwinn Approved' Huret Allvit derailleur. The chain is stamped 'SEDIS'. I think it's the original. I think you could replace it with any '5-speed' or '6 -speed' chain (same as '7-speed'?). I think these are 3/16" width chains (isn't that right?). Just use the same number of links; link pitch is standardized at 1/2". Single sprocket bikes (old Schwinns, BMX) use 1/4" width chains. Not sure of the substitutability of new pins. See Sheldon's site; chains have changed a lot now vs. then.

[EDIT] 3/32" width for generic multispeed, 1/8" for single speed
