I think it's a shaker motor. Looks like it's sorta based on the 515, or possibly whatever it's field coil predecessor was. Seller says 60lbs!
................. and it's pegging my cool meter
the end looks like pin connections to me. ??que?
are you thinking disney?
I'm thinking R&D, laboratory/testing.
Check out that mechanism, bevel gears and rack that moves the thing in it's base. That stuff was tooled separately of the device itself, it was customized for a very specific application, whatever it is. There's even a tool crib ID plate on the base.
yeah, i was looking at the mechanism. and the beveled gears are attached to the stub projecting below what passes for the face.
It's not Altec.
It says Ling Altec. That was the corporate name. Made in England, I doubt it has Altec parts.
I see no electrical connections.
Ling Altec made lots of military. IMHO it's an ignorant seller hoping calling it "Altec Ling" instead of Ling Altec will sell it. A curious piece of mechanical scrap. Nothing more.
Good old Ling reusing obsolete Altec model numbers. The original 408 was a tube type telephone repeater amplifier.

I took the seller at face value when he referred to the connector on top. i assumed "electrical" connector.Quote:
I see no electrical connections.
Your observation spurred more thought, and it occurs to me that if this were an electrically operated device, it would bear electrical specifications on that ID plate.
I have to agree, probably 60 lbs of wishfully misrepresented(but nifty) scrap metal.
I forget that sometimes "Ling" on the label should raise a big red flag.Quote:

Laboratory transducer? May well be.

It says it's a position controlled servo system. Whatever that is. The transducer they mention was hooked to this, so it's not a transducer. That was external to this.
