There have been threads here, in the past, that I've described the course(s) taken when finding parts.
Path A, lead to path B... to path C. Then E-mail this company, and that person. In those cases, it was an adventure.
This time around it was just brute force. Search this possible combination of words, then search that set of words, then search some more... years later... just keep searching.
A few weeks ago, while scrolling through the pages of the whatever hundredth camera and/or vintage equipment site, up from the bottom of the screen came a photo.
There it was!
These came from a used camera equipment store in South Yorkshire, England.
Although... these parts haven't quite given up all their secrets. The shop only had two pieces, and they were listed as "Unbranded".
The shop had no idea whom they were originally made by. When they originally acquired the pieces, they also tried a (very brief) search, and came up with nothing.
These are clamps for a Umbrella flash tripod stand.
Technically they are adapters. Used for attaching a secondary flash to the same stand.
Sorta' kinda' like this:

The center insert can be removed from the larger piece, depending on the diameter of the tripod stand.
One twist knob secures the clamp to the stand, the other secures the angle of the flash/ lamp.
Although the shop did not know the original manufacturer, their best guess was that it might be part of the
Jessops (British photographic company) "Portaflash" brand, or possibly from one of the many (now extinct) minor brands that were created,
by having Chinese factories make budget knock-off pieces, with small amounts of stock, in the late 80's to early 90's.
* The search phrase, that finally landed me on the correct page, was "Brolly clamp".
