Wayne,
if the nose opening at the very bottom measures 0.730" diameter (as
mine does)
then it might be a BS7 (definetly not MT2).
Be aware that there is a third size. B3
I have never seen one of these, however.

The B3 ID is about 0.77" (just checked mine). The taper is short, and
similar to R8, only smaller. The draw bolt is same as R8. If you're
lucky, it'll be one of the others.
