That's close enough to the British (Imperial) standard, which would be 25.4 for the TT, 28.6 for both DT and ST, there could be some interference from paint giving you these discrepancies.
If it were metric tubing, it would measure 28mm for both DT and ST, and 26mm for TT.
So...what have we here? Is it all British or does it have a metric thread (1.0mm) BB shell indicating a Swiss BB (cause of the LH threaded fixed cup) but on non-metric tube set? I'm back to being stumped.
