A couple of notes may be helpful:

1) At least for Reynolds 531, the seat tube was singly butted, with the butt at the bracket. Pity, really, since it would have meant a finite clamping distance, and less likelihood of getting the post stuck. This led to the "funny" Schwinn decals that were carefully worded to not suggest that everything was double-butted. I suspect, but cannot verify, that Columbus worked the same way.

2) This may be urban legend, but it was my impression that the 26.8 ID seat tube was part of the SP (heavy) set, and the 27.2 was from the lighter (SL?) set.

I hope someone better informed than I will comment on these assertions.
