I am not sure what you need to know however when I needed hubs for my 16/80 which had worn splines particularly on the rear axle which takes the reverse loading of acceleration & braking, I expected the hubs would be similar to SS/Jaguar cars which used the same chassis & ENV axles, but they were dimensionally different! So I decided to do an engineering drawing of my hubs & liaised which Orson who were good enough to verify the finite dimensions using there metrology equipment, I was able to arrange for Orson to manufacture small batches of them for sale to owners, initially they made about ten sets of rears & later made the front hubs as well which I re-specified the Timken bearing as the original bearings in my car fractured due to there thin outer ring!
Orson I understand made at least three batches of hubs which sold to owners over a few years, however now whilst the New owners are willing to make these hubs they are reluctant to stock them, so have sold a batch to Mr Briggs who will stock & sell them on! I am pleased to say I have spare hubs for my cars & some of my Customers also purchased them direct from Orson!
If you have wheels then you might find it sensible to have them re-conditioned by a reputable company such as MWS who will check the wheel hubs for wear as well as the rims & spokes etc, I found that the wheel hubs do not wear as much as the axle hubs as they are rotated over there life so not staying on the rear axle all the time, one key issue is to look carefully at the axle hub wear & replace them if too far gone!
