I measure all three knob skirts at 1.482” outside diameter (doesn’t seem to
be around number in metric either.)
I suspect we could use 1.5” without serious problem, although the alignment
of the yellow numbers with the lamp lens will be tricky.
If I remove them again to try and take perfect photos, I will try and
figure out the inner and outer diameter of the alternate markings used when
the lamp is on.
