Dow-Key coaxial relay

I saw these uncredited pictures on Face:

Coincidentally also saw this ad in the October 1962 issue of QST, page 135:

I recall that when I made my first contact at the Nicolet High School radio club:

There was a Dow-Key coax relay that had a corresponding toggle switch (can't quite remember the details of how it was hooked up).  But I had to throw the toggle switch to transmit on the Adventurer and then flip it off to listen on the Swan - definitely not break-in - my HW-16 was so nice in comparison.  As I recall the relay kind of hummed when it was engaged  :)

Semi-obligatory inflated price:

Yikes, consider 10 times the price of some of the other gear in that issue of QST like the HT-37 at $495, wow !!

I did mention the fact that Dow-Key and Digi-Key were both located in Thief River Falls:
