Steeltrack drive gear size?

[JamesF]

I notice the fine focus knob on the Steeltrack focusers has a built-in gear drive cut on the inside of the knob.  Very neat idea, and one which I might steal when I get around to learning to cut gears on the lathe and make a couple of similar knobs up for my own motor drive on my Revelation focusers.

Does anyone happen to know what the gear/belt size is for the Steeltrack?  It looks like it might be a 3mm pitch HTD belt about 6mm wide, but if someone actually knows that would be handy.
