This installation does not appear to have been a AN/ARN-7 from a US military
aircraft setting.  I've never seen such installations use Jones plugs.  It's
likely a civilian installation, or possibly British (with their love of Jones
plugs).  It might even have been a maritime installation somewhere that SOLAS
regulations didn't control, but it would be hard to understand the use of a
two-station control for that.

But regardless, it's all there for only one simple purpose...allow two control
stations for one common ADF receiver.

The long-lived AN/ARN-6 has one specific mount (MT-273/ARN-6) for the R-101/ARN-6
that has all this control transfer system built in to the bottom of the mount.
Much neater!

Now you are describing how equipment may be kludged into serving some
installation that the manufacturer never intended.  ALL bets are off then. :-)

I was sure that you knew the MN-52* isn't associated with the other gear
pictured in Ken's photos...I just wasn't sure everybody who reads did.
