Steve,
If you put a spoked hand wheel on a 99 the diameter on the backside on the handwheel is smaller than in the solid hand wheel.
The bobbin winder now won't reach the handwheel so therefore won't work. The spartan bobbinwinder is simplier,
with no auto stop so it will hinge far enough to reach the handwheel. There are work arounds for the 99 bobbinwinder
to make it work.
