Bianchi Superset II seat post

I have this Bianchi (well, not this one, but the same frame):

I'm missing a seat post. I know I should have digital calipers, but I don't. Sticker says "Superset II" tubing, like so:

Any ideas on post size? 27.2 is too large, by a little. I'll likely take it to the co-op and just start trying some, but maybe the brain trust already knows.

Both my '87 and '91 "Superset" Bianchis take 26.6mm posts, but my '88 Premio (also labelled "Superset") takes a 27.2mm. I think "Superset" was more of a concept than a fixed set of specs, so it's always good to double-check.

All Bianchi frames were built with a Superset or Superset II tubesets. The down tube and chain stays were a heavier gauge tubing to improve the ride. On the Superset II frames they started using downtube that was ovalized at the B.B.

I suspect your post is 26.6 or 26.8. If someone has a 90/91 Volpe maybe they will check it for you.
Bianchis '90 Proto, '90 Campione del Fausto Giamondi Specialisma Italiano Mundo, '91 Boarala 'cross, '93 Project 3, '86 Volpe, '97 Ti Megatube, '93 Reparto Corse SBX

Others but still loved; '80 Batavus Professional, '87 Cornelo, '?? Jane Doe (still on the drawing board), '90ish Haro Escape SLX Bertoni "Speckled Trout"
