The numbers on the bottom bracket casting look like cast in not stamped individually like the frame number. I think 64 is the angle between the seat tube and down tube, very important for the frame builder. Cast lugs could be pulled sometimes up to about 1 degree.
As this angle is now likely to be around 60 on later frames it would mean a higher bottom bracket, on 27s probably 11.25 inches.

Very observant Keith, and knowledgeable as usual.
Do you think, with the high BB and lack of braze-ons, that this might have started life as a bespoke single speed grass racer? :?

I would think probably general use club rider. One bike for everything, time trials, occasional grass, probably ride to work.
Just change the wheels and remove mudguards.

I keep being reminded of things I thought I had forgotten. As you know I was a retailer from 1954 to 1966 mostly in the lightweight end of the trade. It was a very much smaller market than you would ever suspect.

Hi,
Pull the forks and look for numbers stamped into the steerer tube.
Any number matching one of the numbers stamped into the BB shell will be your serial number.
Once you made sure which is your SN, dating/ID-ing the bike will be a matter of seconds :)
