[TMC] Looking for TMC Model MCP Control Panel Parts

[triodes at optonline.net]

Hello once again, fellow TMC enthusiasts!
I am looking for one more (and hopefully the last) item for my TMC 
station.
A very kind and generous fellow TMC enthusiast was able to provide me 
with the mating EBY 2-pin male connector for the GPR-90 muting 
interface, so I was able to successfully connect my GPR-90 into the 
station muting buss. Thank you again, Tom!
Now I am need of either a complete MCP Control Panel unit, or as a 
minimum, one of the 4-position rotary coaxial selector switches. These 
switches were made by DK RF Products in Danbury, CT, and use BNC female 
connectors.
Does anyone have these items? The Model MCP was used in several 
different TMC transmitters, including the GPT-10K, the GPT-40K, and the 
TMC Sideband Analyzer Unit, for which I can't recall the nomenclature 
for at this time.
Again, one of the rotary coaxial  selector switches as used on the MCP 
would do me just fine.
Any help from the group would be very much appreciated!
Thanks & 73,
Bruce, W2XR
