I just got an old JMI NGF-1 with Moto-focus and restored it. This is the 1st generation of the model with the body being polished aluminum and the barrel being black anodized. The Moto-focus runs on an O-ring that runs on a groove in the focus knob. Really I neat piece of work. The Moto-focus works very well, with quite a lot of adjustment in speed settings. I have polished the aluminum back to mirror finish and it looks like new. A real classic as far as focusers go. Not sure where it will be used yet, but it will be a nice addition to the scope. I will post a picture later if anyone is interested.
