Here is a brand new resin facsimile replacement knob for a vintage embalming machine. This was molded from an original knob taken from a Turner Porta-boy unit but may be used on other models. It is cast in urethane resin with a marble filler and has been painted black. It measures approximately 2” in diameter and about 3/4” deep with an approximately 1/4” diameter hole in the back. You might want to mount it by adding a little epoxy adhesive to your unit’s control spindle. I have multiples of this casting available so let me know if you are interested in additional knobs. See photos for overall condition and ask any questions you may have.
