All CRs:
Regarding the "odd" Campy calipers on eBay
my Campy catalog 18B (dated 4/85) shows that these calipers are Triomphe. The half-round cross section of the caliper arms is like old NR and GS. The black pads and black o-ring on the cable adjustment are both NOS. The Triomphe brake levers (which are not shown on the eBay listing) look identical to Campy NR except for the logo, which in this case is the shield with winged QR. NOS lever hoods were tan.
The next-step-up Victory calipers have a triangular cross section, similar to late Campy Super Record. These pads are beige-gray and the o-rings are off-white. The brake levers (also not shown on the eBay listing) look identical to Campy SR (drilled) except for the logo, which is also the shield with winged QR. NOS lever hoods were white.
Both calipers came in the options of short or long reach; both allen or hex bolt mountings were available.
Both of these calipers are contemporaries of the C-record delta centerpulls.
