^^ good find thank you, i'd be tempted to get one if they looks like the one in the picture

Unlikely you'll get one like that.

The owner's words:

                                  Wanted a slightly  longer/lower stem after changing to the 3T bars.  Picked up this  beautiful vintage rare 3T stem that was custom made for Mario Cipollini  who was a massive sprinter. It's aluminum core wrapped with carbon and  is a massive brick, but still light. I stripped off the 3T logos to  match my bike.   

3T only many a few of these stems before discontinuing them because production cost was insanely high. The whole clamping mechanism is internal and tightened by one small bolt (hidden with a cap) on the side. Very innovative design that's super clean and minimal.
