Does anyone know of a Campagnolo tap to make a bb shell accept the old over size Campy Cups? The old catalogue reads "Upon Request we supply the cups with thread increased by 0.5mm"

You can see the os cups were initially stamped 1.370 x 24tpi & the 7 was stamped over with a 9.

Here is a link to an image of the cups on top of the catalogue page.
