I found a picture of Mr. Arnold Rothstein, so must be made before or 1928 with his desk phone assembly. Receiver seems bit strange and never seen before, not even in any old supply catalogues. Obviously for hands free phone calls. Haven't found anything on it here too, so I thought post the picture.

Kinda reminds me of 18th century hearing aids:

As an FYI: Un-affordable device these days.

That's a bargain! My modern hearing aids, if I bought them outright, would be around $7k!
isn't that an early model jabbra? ;D
It's the first handsfree kit for sure... ;D
If you look at the image closely, you can see the butt end of the receiver sticking out below the "adapter" box which connects the receiver cap end to the sound horn, an actual hollow tube horn and not a receiver (wired element & diaphragm) at the ear end. It's a sound powered receiver tube, or whatever they called it.
No more holding the receiver.

TelePlay,
you can even see the top of the original receiver, seems like the original cap was replaced with that hollow tube thingie, or even the tube somehow attached under the receiver cap and coming throu the hole. At least, has to be lightweight if so.

John,
The picture does not lend itself to magnification very well but, the part you have pointed out as an adapter appears to be part of the scissors arm. Probably part of the clamp that holds the stick?
Better picture of the details. I would say same as HarrySmith, looks like the clamp to me too, The receiver can be seen behind.

Some holders are quite simple, as this Kellogg pictured in their 1910 catalog.
That large bracket in the picture looks more like a dual purpose box, to hold the receiver close to the end of the hearing tube and to keep ambient noise out of the hearing tube. Looks like a box with its own set of clamps fitting in between the scissors clamps.
Haven't found the WE version yet, came across this Kellogg looking for something else.
The WE 1916 Apparatus Catalog (page 278) shows 3 varieties of these, all of them having a simple connection to the desk stand shaft.
Funny that should come up around world series time, given Mr. Rothstein's connection to a particular one. ;D
I would imagine the bracket would be changed to accomodate the receiver. It sure looks like it is attached to the scissor assembly.

Agreed. Probably a custom made piece.
Found a picture of a bracket with quite similar look as Mr. Rothstein's : AE Jul. 1939
and another picture I found on the net showing the "big" connection block
That looks very similar. Nice work.
