As far as Campy brake caliper reach, there was only "regular", which came to be known as long reach, and then "short" which eventually came to be known as regular! The Campy calipers that I know to be "long" reach on my 74 Colnago are not original, as it came with Universal Super 68s, but they fit perfectly, measuring about 52mm from center of mounting bolt to center of brake bolt slots. From the archives, using all the savvy I have at my disposal, I gave up at about page 4, trying to find definitive numbers regarding Campagnolo brake caliper reach, so I had to dig into my own files. Below is a copy of text sent to me from Greg Parker (thanks Greg), regarding a similar inquiry I made a few years ago:
>Regular reach is 47-57
>Short is 42-52
>Drop bolt adds 6 in the rear.
>I believe that's partly correct about INTER vs. INT - the late short ones
became INT due to the tight space on the arm. Shorts came both ways, but I'm not
100% sure about regulars (brain fade right now). Short ones also came with
and without the rubber bumper on the >fronts (early, no; later, yes).
So hopefully, this post will make it easier to find Campy Campagnolo Campag Campa Camp Nuovo Super Record Brakes Brake Caliper Calipers Length Reach Long Regular Short Dropbolt and Drop Bolt Measurements Measurement ... in the future! :)

This question relates to my ongoing search to locate all the necessary period correct parts for a 1974 Colnago Super I am restoring. Can anyone tell me what the different Campagnolo brake calliper lengths (short, regular and long) were used for and when they appeared?
