I will be picking up this set in a couple of weeks. I will post a video of it in operation once I get it operating!.
It came from the Henry Ford Museum.

Very cool pick-up Dave. Looks to be in really great shape.

It is in great shape!! It is an actual AK model set! It is a model 1100 I beleive! Not many were sold in 1925/26.
I saw it in person a couple of years back. I am going in a few weeks to pick it up. It is a long drive!

Looks like a set of QRS tubes

Good eye!! Yes they are. I was told they are fairly collectible.

Dave,
This is a Pooley 1300 cabinet. Most I have seen just had the wood horn in the top with a driver. I do know Pooley made this model with a turntable, but this is the first one I've actually seen with the turntable. When you get it, I would be interested in knowing where the driver and horn is for the AK 20C. Also where does the sound from the turntable go. Is it strictly mechanical like a Victrola and the sound just goes into some type of a wood horn to spread the sound. I doubt the sound actually goes through the AK20 and is amplified.

I would really like to know.

You are correct ! It is a 1300 afterall!!
It appears the opening where the phonograph sits is the opening of the bell. It is my understanding there is some sort of mechanical lever to select between radio_phono.

Yes, I will know much more when it is in my possession!

Dave,
Thanks for all the pictures. It shows this to be a Pooley 1500 cabinet. That's why I haven't seen one like it. All the ones I've see that look like it were 1300 cabinets. Most of my Pooley catalogs show the 1300, but I have none that show the 1500 to compare it to. Looks like the 1300 and 1500 used the same cabinet, with the phono being the difference for the 1500.
I will hunt for literature showing the 1500.

Here are a couple pictures from Bob Prochko.

Dave,
I knew I had seen it somewhere in my pictures.

Here is one more!

The literature states to switch from phono or radio one merely slides a lever. I am not sure where or how it operates.

Just a guess, but it may operate similar to how heaters did in some older Jeeps and other vehicles with the cable controls. Basically the cable is attached to a flat plate that either allows warm air into the cabin when opened, or when closed diverts it outside. Is the phonograph motor spring or electric? If the former, it's probably a Saal two spring motor that was used in Pooley branded phonographs from about 1920 onward. Silvertone phonographs of that era used that motor as well.

Under what sort of circumstances are things like that divested of the museum collection?

Very nice, Dave. Looks like you found a winner.

Agree, that is very nice, Dave.
So is the phonograph strictly an acoustic machine, or does it have EM pickup that uses the radio's audio circuitry?

Edit: Ok after looking at the tonearm of the phono again it would appear to be an all-acoustic machine.

It is my understanding the HFM auctioned off a bunch of items around 1995. I purchased from the man who purchased it from the museum.

When they end up with historically ignorant management that want to "Take the museum in a different direction".

Dave, It is absolutely a beautiful set! I was fortunate to help load it and move it around. I have a short video of it I would like to share, but nowhere to properly host it.

As for the Henry Ford Museum auction back in 1995? Here is the report on it in Antique Radio Classified.

I was there and bought a Zenith model 92 console for $300, which is listed in the second issue.

It was quite an auction.

Wonderful!! Thank you for your help!! I will be there in two weeks to pick it up! Glad to hear the phono was operable!

I bet that was one heck of an auction!!
