Hi,
I'm no expert on Peugeots. But the size differance between the largest @ 26.8mm and the smallest @26.4 mm is only 0.4 of a mm. Not much !!
Maybe there were some inconsistancies when the frames were brazed. and this makes the tubing vary? I wonder when the bikes were assembled in the Peugeot factory if, they selectively assembled the seat posts into the frames??
Prehaps there was a conversation in the assembly shop somthing like this. "Oh no another frame from Jean Paul"!! "Quick pass the 26.4 posts some grease and the large mallet".
Who can say!
Regards,
John
