What is inside the tube looks like a handset receiver module.  How do I hook it up to test it?

Found the diagram for the modular version (S1AM Tone Ringer) in the TCI library:
Tip (green) to 3
Ring (red) to 4

Very Cool! I seem to recall an experimental 500 model with an electronic warbler ringer type thing that was on eBay a few years back, same principle?

[wds]

I needed to use a condensor to make it work properly - No condensor built in which seems a little odd.  Now I know what those warblers sound like.

Thought it was a chime ringer until I saw the inside. Virtually the same packaging.

Diagram snows a capacitor connected to 2 and 4 on the terminal board.

[wds]

This one was wired with the red wire coming off of #5, where the resistor is between 5 & 4.  So I moved the red wire to #2 and added the cap. between 4 & 2.  (there was no cap there before).  Works great now.

Here's a magneto with an older style bell on top.  Generator puts out 100 volts ac, ringer nice and loud.  Don't recognize who the maker is for the ringer or magneto.

Found another Warbler.  This has different internals - has the cap and a transformer the other one didn't have.  Has the same sound to it as the other one.

I've seen these before, but can't remember where.  Some sort of Operator Foot Pedal.

Does anyone know what this is?  Can't tell if it's a ringer or loudspeaker? 

It is a tone ringer. I think it is the same technology as the Morris field trial sets. It is HTF.

I don't know what that box is but it looks old, like 1890s. 

The cast iron box with the foot pedal was part of a RR dispatching system.  I think it used a 295AK subset and headset type candlestick.

Found this in a WE catalog.  The foot pedal is part of the 502A Subscribers Set.  Railway Train Dispatching Telephone Systems catalog.  Second picture is a list of the components for the 502A, and the third picture is the wiring diagram.

[wds]

I found the 386 transmitter and the 189 headset that's part of the 502A subscriber set - I'm sure the rest of the parts are on one of the shelves I have yet to explore.

Those two look like test fixtures, or school science class parts...
