I thought early 70's BB's for campag NR were 112 ? One for sale on Hilary Stone's website and I'm sure Campy Oldy might have one.
Are you looking for an original replacement?
I've had the bb out and its a 115 and races are
Pitted .. Repacked with grease and a bit rough with bit of play
Not fussy if original just something that works
Will look at those
