Most Specialissimas have no such sleeve and take 27.2 seatposts.
Sounds more like a Cinelli construction feature - though they take 26.2, not 25.0
Early 60s Specialissimas should have a serial number stamped in the top of the seat lug. I have seen several with 6-digit numbers starting with 160 to 164. What's yours?
