There's a Bob Jackson from the late 70's that sold on ebay, http://ebay.com/<blah> and I'm wondering about the crankset/chainrings. The auction states that the crank is Campy, but the rings are (he guessed) 47-40-28.

"Supersizing" the photo shows a strange pattern to the inner chainrings, and it lools like a 6 bolt inner. Is this a early "tripilizer"?
