General Information
Width measurement (C-C) is at the ends. Width at the brake hoods will be more like 34 cm due to the randonneur bend.
Actual measured clamp size is 25.15mm. There is some reduction in diameter noticeable from being clamped (overclamped?) for so many years.

Date of Manufacturing / Production Code for SR seatposts (at least for the 80's):
The date of prodcution of SR (Laprade) seatposts is shown around the min.insert line as follows:
"letter"-"double digit number", e.g. F-81 oder L-81, while the letter should be the month and the number will be the year of production.
So F-81 seems to be June 1981 while L-81 would indicate December 1981.
