Seatpost Identification

Can anyone help identify this seatpost?

28mm at top, turned down to 27.2 lower down. Clamp says 27.2 on it so original. Clamps like a USE post. Came on an old Pinnacle.

Has a kind of early syncros look about it, but I'm no expert.

IRD seems spot on and an unexpected bonus. Thanks.
