Thanks, it appears the large rivet Pro could have been installed on a Paramount in 1973, although it probably would not have been stock, as Raleigh Pro appeared with it before any other production bike did.
I've visited the Phil site and am now more confused. They seem to the saying that the "Campy specific" BB is ISO and is for Campy after 1994. The site seems to imply that pre-1994 Campy, including everything on topic here would use the "Standard" Phil BB, which is not ISO. Anyone understand all this?

<70's, but can anyone pin down the exact year? I just bought a mint 1973 all-chrome Paramount on eBay. I want to change the Unicanitor saddle to a Pro. I like the team Pro, but it may be just a year or so too new, so perhaps I should use the small-rivet Pro.>>
Gerry,
I don't know for certain when the large rivet pro first appeared, but I do remember seeing one on a Raleigh Pro in the summer of 1973. I really wanted the Pro but could not afford it, and "settled" for a Raleigh RRA instead. The Professional had the large rivet Brooks Pro saddle.
<For C-Record? For modern Campy? Do the Phil "Campy" models just have more offset to the right than "regular" Phils, or is the taper angle different as well?>>
I just got a Phil BB back from them and the spindle measures 113mm. I also took some measurements (sectional thickness) from NR (post CPSC spindle) and C Record spindles, as well as the Phil, and here they are:
At the start (the end) of the spindle: NR (12.75mm); C-Rec (12.85mm); Phil (12.80mm);
At the mid-point of the spindle: NR (13.10mm); C-Rec (13.25mm); Phil (13.50mm);
At the shoulder: NR (13.60mm); C-Rec (13.50mm); Phil (13.90mm)
The offset is the same amount on both the NR and the Phil (5.0mm)
I do have a modern Record bottom bracket, but didn't dig it out at this time, but I suspect the measurements will be very close to both the NR and C-Rec. These measurements were taken a few months ago (with the exception of the Phil BB).
