Can anyone tell me if the crank I am looking for (see Yankee Trader request for Edisonic Schubert crank) was used on other model Diamond Discs?
I see many Edison disc cranks listed on ebay, but do not know the dimensions of the crank I need.
Thank you to anyone who can provide information.

I have an Edisonic Schubert. The crank is 4" long on the knob section and 3 ½" long on the business end.
