I did not get a chance to look the items over again, but I did call and asked the owner of the shop to tell me if there were any other names or marking on the various parts. what he told me was this...
Rear Derailer - # 840
Shift levers - # 821
Brakes - # 440
I did see the rear derailer on ebay for like $12 , So i'm thinking this might not be such an old/valuable group set.
