I have one.  Big, heavy. It has two dynamotors. The crystals are Bendix 
MX-9 units which hold

both transmit and receive crystals.  Bendix's name for the set is RTA-1.

The mounts are pretty scarce, but be aware that there different 
varieties of mounts. My

mount was meant for the a DC-4 installation, and the radio will not fit 
in the mount unless

the outer case is removed. I wonder if the DC-4  installation used the 
structure of the airplane as

a case.

Control boxes are also hard to find. Although Bendix did make a control 
box dedicated to

the radio, one of the instruction manuals says a control box should be 
locally constructed

to accomodate the particular needs of the airplane involved. Not hard to 
do, just switches

and pots.

I managed to get mine sort of playing some years ago, but it has been 
languishing on

a bottom shelf for a long time now, just too many other projects.

If anyone wants it, they can have it, but did I mention its heavy? 
Shipping not an

option.

At one time, I had a Bendix fetish, looking for anything 40s era Bendix 
related.

But I outgrew it.  Only Bendix now is a TA-12/RA-10 setup, as well as 
the little

3801 set.
