Clever dedicated electronic flash bracket for compact camera - maker?

Thanking you all in advance.... I have wondered about the below pictured small (60 x 69 x 22mm) modular flash bracket for a year.

Now i'm trying to ease back into photo.net, and the first thing I have is questions. Some nerve.

I used to shoot with a Rollei 35S, and I've seen many small cameras - this bracket has no maker ID, but it is well machined and appears to be versatile, but for a specific unusual camera -

- It has both plug-in connections, and a pc socket.

So it will accommodate a hot shoe connection, or a pc one?

- The threaded screw will only work on an extruded socket.

(That extrusion needs to fit into the recess around the screw.)

- As the screw wheel is turned, small holes in the back of the wheel are revealed through an opening on the camera side of the bracket.

Perhaps one of the holes turns into position to receive a spring-loaded pin, to keep the wheel from turning during use?

It's the little details like that that kept me interested.

Any ideas?
