I remember when I first purchased my 36 Ruby I had some very old Whitworth spanner’s which I noticed would never fit any new “modern” Whitworth nuts, even though they did fit original nuts.
When I investigated I found pre-war tables which gave larger dimensions than later tables.
I believe, but stand to be corrected, the dimensions were reduced as a means to save material during the Second World War.
If I can find the tables I will post these, but it is probably 30 years since I last saw them!
