Of course they do.  Without trying, I acquired three
RT-427/ARC-39 units since I bought the first at Fair Radio
in 1978 while traveling between duty stations.  But I have
only one that is complete with mount, control box, and
manual.

For a listing of US Cold War sets, I once again call attention
to the USN AN/ARC-25, which is the AN/ART-13 with AN/ARR-15.
Compare it to the familiar USAF AN/ARC-8, which is the
AN/ART-13A with AN/ARR-11.  (The AN/ARR-11 is the JAN
nomenclature for the BC-348-*.)

The "AN/ARC-25" designation seems unknown to many for whom
the "AN/ARC-8" designation is very familiar.

I have both sets complete with mounts, dynamotors, control
boxes, etc.  Unlike the AN/ARC-8, the AN/ARC-25 provides
remote operation of the R-105*/ARR-15.  However, the AN/ARR-15
provides no coverage for the 200 to 1500 kHz capability of
the O-16/ART-13, while the AN/ARR-11 provides coverage of
200 to 500 kHz of the 200 to 600 kHz capability of the
O-17/ART-13A.

I'm pretty sure that other AN/ARC-25 sets must be held by
other folks as well.

FWIW, I think the importance of the AN/ARC-2 and
AN/ARC-39 as Cold War gear was very minimal.

The USAF bought a fair number of Collins commercial HF sets,
namely the AM 18S-4 (as RT-380/AR, part of AN/ARC-59), and
AM 618S-1 and USB 618S-1/MC.  These last two have no JAN
designation.  They are rather different from the two USN sets
with which they are frequently confused...the RT-311/ARC-38
and the RT-594/ARC-38A.

The USAF obviously needed some HF sets that were a lot
lighter and much less expensive than their AN/ARC-21, -65,
and -58 for many of their aircraft.  (The cost of the
AN/ARC-21 set in 2012 dollars was apparently about
$180,000!)
