I am curious to see what keeps the rear brake cable off of the bottom bracket?

The cable runs right against the BB.

Raleigh Lentons: 1948-1960​

...possibly you are already aware of this well documented history of the Lenton bikes from Raleigh.
It has a lot of pictures, and it might help you to look through them to compare similarities and differences.

Yours give the impression of extensive modifications, done pretty well, given what was available at the time.
