Wanted: Winding crank for a Columbia BD or AR

[chrisg]

I would like to find the correct winding crank for my Columbia BD. It requires a slotted crank with ⅜" hole. I believe the outside diameter will be ⅝" with about a 4" drop to the knob. Someone with a similar machine may verify, as I am going by my machine and photos online. Other models may use the same crank such as the AR
I have contacted Ron Sitko & George V. and they didn't have anything
