I have a NEW, never fitted Vixen dual speed retrofit focus knob unit for sale. Has all hardware, instructions etc.
Will fit all Vixen with the newer pinion that secures the knobs with grub screws at side. Will NOT fit older tapered pinions - though I can supply a drop in pinion replacement for $20 extra.

My price for the unit is
$200 posted, or $220 with the spare pinion.
SALE PENDING (sorry Chris, to another gentleman)
