Hi Tam,
The cranks you came across are either Campy Victory or Triomphe from around 1988-1990. Campy made them in two different bolt circles, 116 bdc which had a 36 t inner ring capacity and also 144 mm. They also made an angled (bent) short lived MTB crank with similar design. The 116 bolt circle was nice for putting together a bike with lower gears with a 36 inner ring. I have a NOS long cage Victory changer from the same era.
Hope this helps,
I think I have a catalogue of the cranks somewhere, but that means digging through years of junk. so it won't be soon!
