[MRCA] Value of WWII Radios ??

[Warren K2ORS]

Here's a question for the list,
Last year I donated a bunch of new-in-the-unopened box WWII radios to 
the Smithsonian Air & Space Museum (for which I received a fantastic 
behind the scenes tour, a coffee table book on WWII aircraft and a 
certificate of donation).

Now its time to file tax returns
Any idea of the value of the following BC-454B, AVR20-A1 (receiver), 
BC-458 (transmitter)  all NOS?


Many thanks!
