And you don't need an overpriced photographic adapter, either -- hardware stores will sell you a pack of five 1/4-20 to 3/8-16 adapters for less than half what photo stores charge for one.

Short of designing your own custom camera plate, or modifying an existing one (tricky, if the tripod socket doesn't sit flush with the bottom of the camera), I'd just use a generic plate as needed. It will be off-center, and it will allow the camera to rotate much too easily, but you can blame the camera's designers for that.
The issue I had when trying to use my Zeiss folders on a tripod was 1) the mounting hole is within a "bulge" protruding off the bottom of the camera, and 2) no matter what Arca-style plate I tried to use, the screw was just slightly too long to allow secure tightening. Don't know what kind of tripods were around in the early 50's, but their mounting screws must have been pretty short!
Anyway, I solved both problems by cutting some cork mat to the size of plate, then cutting a round hole in the center of this cork spacer. Fit the cork spacer over the tripod contraption on the camera, then screw on a plate. The cork spacer allows you to tighten the plate right down and, also, helps keep the camera from rotating around. For my 6x9 folder I re-purposed an old plate that had a lip along one of the long edges. Using my cork spacer and ensuring the lip sits firmly against the bottom edge of the camera totally eliminates any rotation.
They are best suited to tripods that combine a mounting screw that is inserted fully, and a tightening nut that pulls down on the mounting screw and camera from below.
The last tripod I had that did that - from the 1970s - was an amateur level Velbon tripod.
There's always 3D printing.
I'm now printing most of my Manfrotto plates, especially when it comes to my home built cameras as I can customize the plates to do things that the manufacturer never intended to.

Yeah, my Gitzo G-1570M head and my Ries A-100 head both do that but the tripods these heads are attached to I use for 8x10. Probably approach the silly side to use one of these setups with a folder.
