THen you weren't paying attention.  Might be a few less on late 3As; but
there were quite a few British fasteners on a TR3.  All the threads on the
SU carbs, most of the threads on the electrical equipment (starter stud,
starter solenoid, mounting screws for instruments, etc.), and a fair number
of threads on the body; like Tenax studs, door lock mount plates, and the
machine screws that secure the soft top straps to the body.  Even the
factory jack takes a Whitworth wrench !

Surely you noticed that a standard wrench doesn't fit the damper covers on
the SU carbs; but a Whitworth wrench fits perfectly.
