For Sale Novoflex Noflexar 105mm f/4 Auto Bellows Lens - M42 mount

I have a Novoflex Noflexar 105mm f/4 lens for the Novoflex Auto Bellows. The lens has a Pentax M42 screw mount. I've adapted a Pentax Bellows to Nikon F-mount and that's how I've been using this lens. There is no auto/manual diaphragm switch, you either have to use it on auto extension tubes/bellows, or tape the auto aperture pin down to get manual aperture control. There are a couple specks of dust inside but that doesn't seem to affect image quality. Looks like similar lenses go new for about $300-$400. I'm not sure where to price it. How about best offer? I can post photos if requested.

Since I don't use PayPal anymore, contact me by PM if you are interested and we'll figure out payment options.

I just noticed that I never said this item was no longer available (but I did close the thread). So, FYI, it is gone.
