I still have some of those from my Triumph motorcycle days back in the 60's.
That is correct, I had them for my BSA bike and Austin car.
To confuse everybody the size on the wrench gives two systems sizes, the BSF and the BSW. For example, a 3/8 BSF has the same across flats size as a 5/16 BSW. Both systems use the same basic thread form, 55° as opposed to the standard US 60° included angle of the thread.
The only use I have for them now is my Myford lathe made in the UK in the fifties.

Reason: info corrected - hopefully.
