Mystery object

[janesdsg]

Does anyone know what this piece of kit is, please, made by Astro Engineering. It's metal, not plastic. I've tried contacting AE but none of the links on their website seen to work.

I have no idea but I think knowing it’s size may help others.

I had a quick look around and see Astro Engineering used to be closely tied to Telescope House so I went to their site and found this. Maybe it’s a part of this observer tray. 
I've added a screen shot for convenience.

Handset holder that fits into a spare 1.25" hole in the tray.

I knew that right from the beginning,  I was just curious to see how long it would take anyone else to figure it out. 🤥

Thanks for all the responses and, yes, it is 1.25" diameter, and thanks for solving the mystery 👍👍
