Beacon and stabilizer found parts?

hi TDH !
I apologize in advance if i make a mistake. I found accidentaly some pictures of drum an clip-on microphones of which the shape is pretty close to the beacon's one. I post some pics below (but it's recent models) so you can say to me if there's a chance that this idea is a good one.

On all you can see the little opening which exist on the beacon

For the stabilizer, i believe that it's the micro holder. I found an pic in google but lost it.
I will continue my research but perhaps if any member know a specialist who had worked in 80's years, he can recognize the brand and model.
EDIT --- I just find the picture of the stand :

Hey Strum,
I applaud you on your efforts.
However, the stabilizer has already been identified.

The Beacon has yet to be positively IDed, but it is "believed" to be some sort of Dentist's drill or suction device.

Keep up the hunt, you never know when you'll discover something.

Thank you very much slave1.
I apologize because i create a new thread rather than post in an existing one (have no excuse because i had already read them but i forgot them)
So i will continue the hunt for the beacon. And with chance...
Thank you again for your nice comment.
