Gates Patchbay

Anyone know what this gates patchbay was originally used for/with? The labels on the top apear to correspond with some osort of master section on a mixing console.  We have "PrgMonOut" "PRGMonIn" "Pagein" A bunch of different cue amp inputs,. a few pairs of speaker, and a single Mic output labelled. I have never seen one of these before, and dont know much about vintage Gates gear.

I have been hanging on to this for a looonnnnng time and dont have a use for it. If anyone has a use for this feel free to drop me a line too, I might be convinced to let go of it.

It's just a Gates branded patchbay, not from or for any particular larger assemblage.  Mid 50's by the badge style.
