Reading on here the original two bolt mechanism is the Campagnolo 1044, but there's also the Sugino Mighty.
There's also some Nitto seatposts but they seem to be only 27.2.

So can anybody suggest an adjustable seatpost (27mm) other than the above ?

Sakae Ringyo made two-bolt posts in both the Campagnolo and Simplex styles in a range of diameters:

Adjusting the Campagnolo style two-bolt posts is easier if you have the right tool; a 10mm flex-head ratchet:
