US Army Air Force military I-193-C Tube Tester Korean War EXCELLENT not tested

Description

You are bidding on a US Army Air Force military I-193-C Tube Tester made by Applied Allegri Machine Co. serial number 616.  The lot includes original operator's manual in excellent condition, four Western Electric METROPOLITAN 255A Polar Relays, and the original power cord and another test cord/probe.  The tester in its box weighs probably 50 pounds or more.  The box shows some cosmetic dings and blemishes from the about 70 years of storage, but the box mechanics are good, and the apparatus inside looks practically unused.
The apparatus is mounted on a chassis that is shock-mounted to the box.  A detail photograph shows one of four rubber bushing shock mountings, one at each corner of the chassis. The box appears nominally water resistant, with a rubber seal (in good condition) all around the perimeter of the hinged top.  When the spring loaded clasps are closed, this rubber seal is compressed to seal the box tight.  Corners and edges are steel reinforced.  This rig is definitely atomic age mil-spec!
I have not plugged in - energized - the tester apparatus, nor would I know how to test it.  I expect that to safely test and/or restore this machine would require a controlled power supply and proper test equipment, which I do not have.  That said, the overall good looking condition suggests that it may well work.  The manual says 1951 on it, so I suppose it is from the Korean War era.
I have googled all possible terms for this particular tester, and have found zero information about it - no pictures anywhere online match this tester, nor have I found any kind of documentation.  Between this and the apparently low serial number, I think it might be quite rare.  If you have any information about it, I would appreciate learning that.
Because I cannot test it, it is being sold AS IS.
It is very heavy, and I honestly cannot think of a way to ship this without building a sturdy wooden crate around it (or simply pasting the shipping label on the box as it is).  If you want shipping, we need to talk... you advise me of a good method.  To avoid the shipping cost/difficulty, if the winning bid is over 0, then I'll also drive to within an hour of Charlottesville, VA to meet with you, to deliver to you.  If over 0, I'll also drive to Washington, DC or Richmond, VA or Roanoke - we'd make a day of it.  Communicate with me about your location, and let's get it figured out together.
If we must ship the thing, I will call it a 69 pound item (that gets it within USPS retail ground parcel weight limits).  I should be able to crate it up within that weight limit.
