Though several responses agreed that they remembered a T/R switch that
looked like it, it turns out that the answer was sent by a person who
"According to the Dow-Key ad in my 1963 ARRL Handbook, it is an RFB
Preamplifier. "50 to 75 ohm impedance matching 'broadband
preamplifier.' Increases overall gain by 1 to 6 S-units on all bands
(1.6 to 30 mc.)"
His memory is better than mine and I remember now and will take a look
in the 1963 QST volume in the library!
THANK YOU ALL!!!!

Along with some other equipment I acquired what I believe to be a
1950s, early 1960s TR switch.
I recognize the power supply it's attached to as a modified AMECO
unit. I can't remember the details of the unit in the foreground of
this picture which I believe is a TR switch. I also seem to remember
it being late 1950s to early 1960s vintage.
