Hamilton Bell V6500 timer knob D shaft with set screw HBK008 New in package

You're purchasing a single timer knob, new in its original RPI packaging. These knobs fit on a D shaft and have a set screw in the back to further tighten the fit. HOWEVER! The front of the knob is oriented backwards from the standard timer knobs that come on the Hamilton Bell centrifuges. I always had to install the timers 'upside down' for these knobs to align correctly with the minute markings on the face of the centrifuge. For that reason alone, I'm offering these at a lower price than the standard timer knobs (see my other listings).

After the ebay fees and my 10% stripping/handling fees (these centrifuges don't strip themselves of parts, you know!) the remaining proceeds of this sale go to my favorite non-profit organization: my local chapter of Sweet Adelines International. I thank you, and the Chorus thanks you!
