RC-18 /working equipment/tubes NBO

I recently came across a manual (1956 RCA receiving tube rc-18) w/spare tubes from the army signal corp. & electrical, tube, (etc) tech books dating in the early 1940's. Also, there are fuses and other parts. some w/their shipping dates and many w/the company names right on the unopened boxes. Included in my findings is a working radio/recorder (?) unit that has enough parts to build another or replace existing parts. I can gather from my research that this piece of equipment was used in the war itself (WWII). I would like to inquire about this equipment to anyone who may know or be able to direct me to the proper place to find out more about this fascinating device! I have seen some 411 in the history museum online, but I need more. If you or anyone you know out there could point me in the right direction, I would be ever so grateful! Anyone know it's value? Thank you for your time & efforts, Apryl
