Please Help ID This Mystery Pantograph

Got a box full of parts along with a purchase of a Colnago Superissimo today. In the box came this campagnolo seat post adorned with a mystery pantograph. Any help with the ID would be appreciated.
Thanks,

Fairly certain that's a Pogliaghi panto. SP = Sante Pogliaghi.

Looks like you're right, just googled some images and found the same logo. Never heard of Pogliaghi. I'm guessing this seat post a little bit rare then?
