How certain are you on this chronology? I have never seen a script-logo on a NR/SR caliper except those having the "Anniversary" profile. Also, I have never seen a script logo caliper of any kind that was normal reach. By the time the script logo came around, normal reach was far from the norm, and as far as I know Campy had either stopped making the longer calipers or was producing a small volume of the block logo variety.
> Chronology of side pull brakes
\r?\n> Normal Reach w/No lettering on arms
\r?\n> Normal Reach w/Block lettering Brev.Inter.
\r?\n> Short Reach W/Block lettering Brev.Int.& rubber
\r?\n> Normal & Short Reach W/Script letters
\r?\n> Normal & Short Reach W/Script letters & Anniversary
\r?\n> Or something to that effect.
\r?\n> My question is regarding the frame types that needed
\r?\n> different arm lengths for brakes to function
\r?\n> What are the determining factors other than actual
\r?\n> Any general rules of thumb? Like year made/country
\r?\n> of origin/
\r?\n> manufacturer/wheel-rim combination.
