Yeah, Bernie. I saw that when it was posted initially, and was somewhat intrigued.
After studying her for a while, I started to think it was overkill for an exhaust throttle.
Looks like it might have a nice application on a TeeDee, coupled with fuel throttling, ala
the medallion exhaust/fuel throttles.
Appears to be a one off, by a talented machinist.

It might be a little hard to open/close the exhaust gate when the servo arm is in the wrong position?
The servo needs to go front to back to open/close the exhaust gate.
The servo arm is 90° to that so the servo would have to be mounted on the side of the engine (and not behind it)?

Probably inspired by the mini and the espo larousse f1 cox engine rc control exaust

It could easily be rotated 90 degrees.

The back clamp looks like a casting, maybe the other aluminum part too. Some kind of production attempt at one time. I bet there are more, not just a one off IMHO. Wonder how well it works.

I don't know who made it but I like it!
Would be fun to give it a bench run.

This piece must work well simple but effective maybe just little on the heavy side compare To rc ring
