I placed a photo of an MX-XA-9/ARC-3(XA-1) at 
http://members.cox.net/aaf-radio-4/ARC-3_XA-1_box.jpg.  It's about the 
same width as the box on the rear of an AN/ARC-1 rack.  I haven't had 
any time to delve into its internals...the plug looks like one from the 
VRC series with that coax pin, dunno for sure.  It's a strange mixture 
of ARC-5 bits and pieces - there are no ARC-3 parts on it that I can see 
externally.
