Thanks Peter,
An excellent source of detail !!!
I also found lots more info and analysis on the following link. Valuable info on Baylis Wiley "cassette" and Wright oil bath hubs too.

Fascinating reading, perhaps the most detail I have ever read regarding any hubs :)
For the CR archives the bearings are known as KLNJ 3/8 Y.
Did-You-Know .... The only Harden hubs exported were 500 cartridge large flange, in 1947 to Australia to Bruce Small & Co (AKA Malvern Star owner and overlord).
