There aren't many, but this is an item I think should go in your display case and never be used. Forget tapping a frame. One cup over-stamped. The other not. How much better does it get? Just too unique.(Or maybe not) Just my 2c.

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.
