Seeking BSP 502-624-(100?) or At Least Diagram For WECo Call Director 624A10(M)

And last set:

125401 - A set of three contacts at the bottom of the module, these are closed by any key press in the column rather than tied to the specific key being pressed.

125408 - Shot of the mounting block with receiving 50-pin connector.  With the modules all removed three such connectors are in this block.

125549 - Shot of the very last key in the very last column.  In this case the small locking screw is not present, so the depression of this key neither locks it in nor impacts the lock of other keys.  I've seen this on other key modules, so probably a stock occurrence rather than something someone removed or modified.

Anywho, hopefully there's some useful information there for someone else coming across one of these.  I don't have the heart to draw up a wiring diagram from it because again I have no way to guarantee anything is actually matching spec, this is not a 1A2 by spec so getting it working on my KSU, while proving the hardware is good, would be a step in the wrong direction.

I'm going to make a classified post for this phone and refer to this thread for photographs and information.  I have no real use for this phone and am not in the game for collecting so I want to get it into the right hands so it'll be taken care of, hopefully checked out against spec, maybe even used with an ESS setup somewhere, who knows.

Interesting phone.
Do any of our forum members have a ESS?
I know Weco355aman (Phil) has his own Central Office on his property.
But I dont think he as a ESS yet.
