Want to Buy WTB: Rapid-wind "handle" for Canon bottom trigger RF camera

Please see the attached photo. I'm looking for the black knurled "handle" or "grip" that you see mounted on this bottom-wind Canon RF camera. I've already got the VT deluxe, so need just the handle.

I can buy a modern equivalent on the known auction site, but what's the fun of that? I'd rather have the original device. If you have one and don't need it any longer, please drop me a PM with your asking price. Thanks!

I had a Canon SV-IV with the bottom rapid winder and a Canon external bright-frame viewfinder; it was a great system for shooting basketball for my college newspaper in the late '50s. Wish I still had the camera.
