Recognize this lens support foot on Rollei 6000 lens?

I'm trying to find a tripod mounting plate that matches this lens support foot on the 300mm Tele-Xenar. Is this some Rollei specific part or is there a universal fit solution so I can mount an anti-twist Arca plate on it?

30 seconds later update. I actually just found the Rollei part after looking for a long time yesterday. Since I can't delete the post, maybe somone can still answer whether there are 3rd party adapters for this lens mounting foot?

It is a Rollei plate, you might be able to find a clamp for it. But it would be easy enough to screw an Arca-Swiss type plate to it. Try to find one that has room for 2 bolts or has a pin that would fit one of the holes in the lens plate. Something like this might work with an adapter in the DIN socket. https://kirkphoto.com/lens-mounting...lti-use-lens-plate-klp-260-with-2-screws.html

That looks like a better solution than the Rollei clamp. The Rollei one I've found mounts with the dovetail, but itself is only single screw for attaching to a plate or tripod. Thank you.
