I've never come across this motor before, but according to the above link, your motor is an A.P.M.
The Aeolian has a Type M.1., which appears to be the single spring version of your motor. (a Type M.2. maybe?)
I've never heard of A.P.M. before, and didn't have any luck finding out online, not even searching "The Gramophone" magazine.
Can anyone educate me as to who A.P.M. were?
The owner of the website must have got the information somewhere, so perhaps he could fill you in on the details of the motor.
If I hadn't come across this APM reference, I would be leaning towards this being a Garrard manufactured motor.
The design of the knob on the crank, I have only ever found on Garrard motors, and on UK Columbia branded motors that were made by Garrard anyway. The design of the metal part of the crank I have never found used on a Garrard however, but I have seen the exact same design used by Thorens numerous times.
The ratchet assembly appears to be Garrard, as does the speed control assembly part of the motor.
The governor however looks more like a Thorens than a Garrard though.
I can only get to 2 of my Garrard double spring motors atm, and both of these use a separate barrel for each spring, but your barrel look as though it matches those used in some Rexonola motors made by Thorens.
The only motor I have that uses a one piece cast motor frame with threaded bearings like yours, is the Garrard super motor too, so it would seen whoever APM was, they were copying designs from both companies & combining them.
There is also a chance these motors were made in Switzerland by Thorens, but I'm yet to come across a Thorens motor claiming to be British Made, but several times I have seen Thorens soundboxes that make this claim. Then again, Thorens weren't in the habit of include patent numbers on their products.
Thorens also copied some Garrard designs. The "Swiss made" Aeolian No.7 motor is almost an exact copy of Garrards first motor, the 1A, except the position of 1 of the 4 screw holes used to attach the motor to the motor board has been moved by ½", otherwise the two motors would have been interchangable.
The AV has exactly the same brake & speed control as your machine/s too, so I wonder if APM did make complete machines that outside companies could buy & label as their own?
I also notice the AV above uses exactly the same lock as my Regal portable which claims to be manufactured in Australia, but it is actually completely manufactured in Switzerland by Thoren. The same machine was also sold as a British Edison-Bell, and they are even a similar design as the AV above.
This could be a coincidence of course, but it's got me wondering if APM was actually a Thorens owned company operating out of England.
