PlanetX Holdsworth Gran Sport bottom bracket

These are very cheap (£8) but has anyone else found they are rather undersized?  I measure the thread major diameter as 1.36" (should be 1.375") and they screw in rather too easily with fingertips.  Going to compare to a Shimano cup when I find one in the bits box.

A UN55 is slightly bigger (and tighter).  It's nearer 1.37" than 1.36", anyway.
