[Milsurplus] Think MAB, DAV and DAV-1

[David Stinson]

Think the MAB Marine corps HF portable,
one of the answers to the Army BC-611:

First came the MAB, which you all know.

Later, an  adaptor (now uncommon to rare)
intended for direction finding was built into an angled
bakelite case that matched the MAB case and
attached to the top of it.
When this adaptor was fitted
and a different radio chassis was installed,
the MAB became a DAV (no suffix) direction finder.
It was, apparently, four-handed and unreliable.

Last came the DAV-1 and -2, built from the
beginning to be a DAV-1 / -2 direction finder/xcvr
and built in a wooden case.

The radio chassis for these three iterations
looks the same at first glance, but they are not.
The single connector on the MAB chassis has one
center pin.  The DAV chassis has *two* connectors,
a six-pin round being used to bring out the antenna connections.
The DAV-1 and -2 chassis goes back to one connector
that has five center pins.

Does anyone have, in their junk box,
one of the chassis for DAV with two connectors?
I'd trade or pay well for one, since I need it
for my DAV.

Thanks much,
David S.
