I'd like to sum this thread up with what's been decided, for the sake of future searchers.
1: The pedals I sold were first generation C-record (Gruppo of engraved logos) aero-triangle pedals from late '85-'86.
2: These pedals were the only style Campagnolo offered in the C-record group in the first gen.
3: Campagnolo originally purposed them for both road and track use.
The C-130 pedals were Campagnolo's first 'track specific' design and were a short lived, interim product that were available only in '86-'87 and were the first C-Record Keirn certified pedal.
