[Milsurplus] MN-20E Loop questions

Mike, a couple questions:

The MN-20 loop: that must be a low impedance winding, right? which couples
via another low Z winding to the tuned RF circuit, right? My question is:
what do you think the "top end" as far as upper frequency limit would be,
coupling the loop winding into the low-Z input of an aircraft receiver?
Possibly limited by selfresonsance of the loop's winding? Ever tried this
for, say, HF dfing?

Now on G&G: what year did they actually end? I was very surprised to
ready that they, at the end, had only one floor. When you see the original
catalog, with NIB ATBs and SCR-583 s and all kinda other stuff, you would
think they had a huge, huge warehouse. Maybe- just may be, they didn't
have all that many copies of each item.
I wrote G&G in 1972 for a quote on a BC-348 and BC-312. I got an answer
about a year later, but by that time i had lost interest. I  did call the store 
once, i don't recall what for, and the man told me he had bought BC-312s
from France and rewired the HFO to work as intact  receivers again, they
had been used in diversity reception in the French military.  
Much later, when i tried to call them, sometime in the 80s, apparently the
owner has passed away, but the phone number still rang and rang for
months after. -Hue Miller
