Serial number or frame number?

Frame numbers on the screwed & glued bracket and Alan, 
food for the other Alan, Turing if he was still alive.
I took some Alan-frames and made pictures of the numbers under the bottom bracket, the rear dropout and, if available, of the date-numbering on the seat tube. When it's not readable anymore I noted a point. 
At first you'll see a picture of the complete frame.

Far as I see,
there's no correlation between the number under the bracket and the age of the frame,
frame number is not the same as serial number.
But maybe there's someone much smarter than the writer of this.
Until than there's the Classic Alan Guide from Piero Zanini, 


check the web for the latest version.
And of course from the end of 1979 the numbering on the seat tube.


Please note,
this is in English because most people cannot read Dutch.
