Kenneth Novak sold this focuser in the 80's and early 90's. It is a flat base 1.25" low profile rack and pinion cassegrain focuser with the pinion gear lines machined into the drawtube rather than on the usual "rack" that is attached to the drawtube. (This feature is very important so the drawtube will fit inside a C8 baffle tube).
If anyone out there has one of these let me know your condition and price. Cosmetic problems I don't care about. Thanks for looking, Bob.
