Oh yes, of course.  There are also some other odd sizes found on a TR3, like
the 7/16-32 threads on the shift lever, and the M5-.75 threads on the tach &
speedo mounting studs; not to mention BA (British Association) threads in
many places.  I was only trying to list the NF sizes used.

1/4-27 isn't listed in my chart; but there is a 1/16-27 NPT thread that is
only slightly larger than 1/4".  And there are a few NPT threads on a TR3 as
well.
