Old pull box

My name is Andy and I’ve just joined the forum. I’m in the process of rationalizing my mom’s estate and found a Signal cash-200 fire pull box that my late father had picked up somewhere. He did some wiring in it so that with a battery attached, the bell would ring and light bulb go on when the handle was pulled. I can’t seem to find any information on this and was wondering if anyone had seen one before?

Thanks!

Stupid auto correct-
Signal csh-200

According to a quick Google search I did just now “Signal Engineering & Manufacturing Company” later became “Wheelock Signals, Inc.”. Here’s also a 1938 Wheelock/Signal Engineering catalog that I found, which features the very same pull station you have on pages 6 & 8 (which gives an idea of its age):

Thanks! That explains why I didn’t find it under the signal name
