Not Too Shabby For A Reproducer!

[Starkton]

Very nice "toy", indeed!

Do you bought a "Duplex Speaker" or a "New Duplex Speaker" (with the body made in one piece)?

Does it really "increase the clearness of the music, by utilizing the vibrations from the under side of the glass diaphragm"??

You know, it doesn't look half bad on a Class M, either.

What's that glass thing on the left with wire coming out of it?

[OrthoSean]

It's a battery.

A Grenet cell battery -- that is what powers a 'Class M'. Practical spring motors came after battery motors. The upper portion of the 'Class M' mechanism unbolts from the lower part and may be fixed to a spring motor-powered bottom (Google 'Amet Motor' for another example). This is the genesis of the Edison 'Spring Motor Phonograph' powered by the Frank L. Capps-designed three-spring 'Triton' motor, which morphed into the 'Triumph' and laterally developed into the 'Concert' -- and 'Idelia' eventually.
