KS-8529 Meter

Here's something interesting which I have not previously encountered:  KS-8529 Trunks Busy meter.  I was told that this was used to monitor traffic flow in old PBX systems.  Meter is a Weston model 430 and probably dates to the late 1940s or early 50s.  Sits on a custom-built wood base with metal bracket.  Green felt on bottom.  There is actually a BSP for this arcane relic (084-645-101), but I have not yet been able to find it.  Any further info would be welcomed.  This will look cool sitting on top of my 555 switchboard.
