Hi John,
If the large knob looks similar, it will work on your scope. Mine is a rack and pinion also. Read the tutorial and make sure the inside of the knob is the same shape as it goes though the bearing. If it is, just measure the diameter of the knob at that point and let the folks know this size as you order the kit. Include my name so they know which one you're talking about. Good luck. Danny Vagg

Just taken delivery of a WO GT81.
This scope is none DDG.
Will this focus system work with the rack and pinion on my scope?

PS from looking at my focuser and comparing it looks similar.
