You likely won't find much, and what you do find will likely carry a rather bodacious pricetag. 

Consider the purpose.  Clandestine.  Not likely to find one of the 300MHz (you read that right) spy radios used in WWII in and over Europe, as the whole thing was Classified even long after the war was over. 

I'd imagine a complete or complete enough to restore Suitcase jobbie would be unobtanium now, or nearly so. 

But there's nothing wrong about investigating and keeping your eyes open, never know.  Just trying to tell you that, in over 6 decades of hamfests, surplus electronics houses and yards, computer shows, perusing of gummint auction junk, etc. I've never seen what could be termed a true "clandestine" radio set of any kind.

Some years back, I was given a complete A MkIII in its original suitcase with morse key and headphones. I had to replace a capacitor to get it working, but I haven't tried it for some years. The going price for that in the UK is pushing the equivalent of $3500. All Loktal tubes, 7C5 PA.

I was also given an MCR - Miniature Communications Receiver, with a full set of cpoils. That uses 1T4, 1R5 series tubes. I haven't tried it yet, and it's only a general coverage rx, but would fetch around the equivalent of $450.

These things are getting very expensive at the moment......

Do a GOOGLE Search (and YouTube videos) on: Paraset
That will provide a weekend worth of reading, viewing, parts lists, and how to build your own!

The Whaddon Mk VII - Paraset Clandestine Radio was developed during the WWII (1941 - 1945) in England for resistance groups in Europe.
http://www.sm7ucz.se/Paraset/Paraset_ex.htm
In 1990, a Belgian radio amateur, Joseph "Joe" Le Suisse, ON5LJ (SK), was one of the first who built a copy of a Paraset.  Using a surviving WWII Paraset (museum), he created the schematic and mechanical drawings from this original unit for those desiring to DIY this historic radio.

Jo Scholtes, ON9CFJ made more drawings from the ON5LJ work.
In 2001, the Italian radio amateur, IK0MOZ built more Paraset copies.
This is the most popular global DIY build for this WWII radio.

The A MkIII and the B2 were rather more sophisticated than the paraset, though, having superhet receivers and two valve transmitters, and a bit more power. The B2 had a 6 volt vibrator supply: the designer (John Brown)eventually became an amateur.

Wow!  This is becoming an expensive proposition.....I would imagine these types of radios are a little more common in EU than over here in the states.....still, it's would be quite the endeavor.....what a history!....

That was not true for the Paraset.  
As noted, ON5LJ did much of the initial work for documentation of that WW2 radio that we have okay.  
Some found there way to US or Canada after WW2.  Mike Tyler, WA8YWO is in West Virginia (not that far from you), has built a few Parasets, that he has documented.

As Peter has noted, the larger radios are also rare -- hence their current price (now historical collectible).

Back in the 1950's they were available for what was then $20 or so - which I suppose wasn't that small an amount in today's $.

Jethro Bodine had one when he was a double-naught spy, too, but I couldn't find a photo of that one.
