Subject: [CR] Seat post query

Since most of the frames that this list are concerned with were made of 531 or Columbus, what accounts for the many different seat post sizes? Even in my very limited collection I have 5 different sizes ranging from 26.8 to 27.2. Did the tubing people make tubes of the same kind (for example, 531 double-butted) with different internal diameters? Certainly would be more convenient if all British stuff was 27.2 and all Italian 27.
