yeah, those Whitworth Phillips head screws used to get
rounded pretty quick.

Y'all must be very young. By the 1960s Britian had
adopted (BSS?) bolts using
US wrench sizes but with slightly different thread shapes.
However, a few
Whitworth sizes were still found on accessories like
carburettors, dampners and
dynamos. Six-point US box wrenches would fit all but a
couple of them OK.


And anybody who's ridden / wrenched on them would know this,
unlike BB, who's limited knowledge comes from Google
searches.
