I've always had a soft spot for the Gran Compe stuff - there's such a huge variety of it out there.
The earliest Gran Compe, I believe, was a heavily engraved rather ornate lever almost akin to the Shimano arabesque stuff. Had flip-releases built in to the levers. Later came (what I like to think of as) the "Diacompe 'GC' Ranch" branding, backwards sans-serif' G' atop the 'C'. Many varieties of lever blades, solid, slotted, also barrel adjusters etc. etc. I don't know the exact dates.
It seems that the RGC and A(ero)GC came later, mid-80s yes.
There are several scanned catalogs out there, mostly on Japanese collector sites illustrating the complete line up. Aha (tinyurl links to google translation of material on the http://cyclotourist.web.fc2.com site): http://tinyurl.com/diacompe-1986
Ooh, and here's a new page I hadn't previously seen, a real treatise it would seem! (attn: Amir...): http://tinyurl.com/japan-brakes
Don't forget the forged Gran Compe stems often seen in .833 steerer sizes - were these ever available (here?) in 22.2? I've a real nice hollow/milled version on my Voyageur 11.8...
