I used to repair, service and restore old malt / milk shake mixers. Accumulated a lot of spare parts over the years and am now going to sell some of my extras. 

This listing is for ONE new-old-stock Speed Switch Knob for the classic 3 spindle Hamilton Beach malt mixers (models 40 40dm 940 940dm) that typically came in green/jadite or cream/ivory colors. These knobs were probably made in the late 60's or very early 70's. These knobs are mounted on top of the mixers and regulate the low-med-high speeds of each motor. Each mixer has 3 knobs so if you want to replace all 3, need to purchase 3.

I will include stainless steel lock washer and screw with the knob (new hardware).

These will not fit any other models of HB malt mixers.

Sorry, malt mixer pictured is for example purposes only and is not included in sale. One picture shows two knobs so you can see front and back but auction is for 1 each. 

Please let me know if you have any questions.

Also, as a side note, someone pointed out that these knobs appear to have also been used on some models of vintage DIEHL table or desk fans.

If you intend to purchase more than one different part, please use the Add To Cart feature and then the check-out process will be more streamlined. Thank you.
