0.8 MOD gear 65T (for Canon FD800 F5.6)

This is a 0.8 MOD gear 65T for Canon FD800 F5.6, that is intended to be used with Tilta Nucleus-M wireless lens motor (https://tilta.com/shop/nucleus-m-motor-kit-i/ ) for wireless focusing control, or ZWO EAF stepper motor with 54T gear (https://www.prusaprinters.org/prints/124287-08-mod-gear-54t-for-zwo-eaf-stepper-motor) for automatic focusing control .

Since the fitting is tight, I apply some lubricating oil first, then carefully push it onto the turning knobs of the focuser.
