80s Fuji 331 Cro-Moly owners: seatpost diameter?

Hello all,
I have a 1982 Fuji "10th Anniversary Edition" (seems to be based on the S12-S LTD). Thread: https://www.bikeforums.net/classic-vi...niversary.html
It came with way too small of a seatpost and the clamp was overtightened to make it fit. I need to determine what size seatpost to replace it with.
I was able to get a 26.4, and then a 26.6 to fit after doing my best to spread the metal back to its original shape. I think it's at least a 26.6, and right now the 26.6 is actually a tight fit because the lug is still a little bit deformed. It certainly won't slip as it is.

So, here's my question, directed at the owners of any early 80s Fuji with a double butted 331 Chrome Molybdenum frame, like the S12-S, or the Professional, or the America, or the Team Fuji: what size is your seatpost?
Thanks!

Interesting, thanks. My frame must be different. I just can't see a 27mm seatpost fitting.
Anyone else? Maybe someone with an S12-S LTD?

My 1980 S12-S LTD came with a 26.6mm seatpost (Sugino SP-H).

Thanks. I guess I'll find a 26.6mm seatpost. Maybe this one:
Sunlite Alloy 350mm Seat Post - 26.6mm Silver
