Hi All,

We have an old (at least 1960's) Wild Heerbrugg Stereomicroscope that 
needs a new fine focus.  The model number is M7 S and the bit that
is broken is the rack and pinion with the focusing knob, they mount to
the microscope stand and the microscope head mounts into them.

Anyone out there know of someone who might have this part or a 
substitute? The scope is a nice one and we can't afford to replace it 
right now.

Thanks,
Karen Pawlowski, Ph.D.
