I don't recall when or  where I got this thing but it was a long time ago and had no idea what it was.  It survived several equipment purges here at W1RC over the years because of the cool decal on the top.  Anyways this web site tells me what it is…..maybe.  I only have the  piece on the right with the aircraft mount.

The APW-11 is mentioned briefly here.

Seems like this thing is part of the ranging guidance system for a 1950s vintage cruise missile.  

Regardless of the “cool” factor it is time for it to find a new basement in which to reside.   It looks like it was removed from service.  There are no vacuum tubes inside.  I will entertain offers around $100 for it.  Shipping will be at my cost.
