WTD: Campy C-Record Aero seatpost, 26.8mm

[CW]

Hello There.

As title says, i'm in the search for a Campagnolo C-Record Aero seatpost in 26.8mm and in good condition.

I want to buy it or change it to a likewise Campy C-record Aero seatpost in 27.2mm instead - also in good condition.

Im not looking for the normal Record Aero seatpost, or any other models (Athena, Chorus etc.) Has to be like the one on the picture below:

Best regards
