I got these with a bunch of other holders and I have tried to identify them with little success. I think they are manufactured by Fujoseiko. I have measured the critical demensions (in inches) and those are below. If you have specific questions, just ask.

Shaft diameter .873"
Thread OD: .780"
Mounting shaft length: .906"
