Years ago, (in the '70's) I recall reading an ad for a place that had 5 original Enigma machines for sale. I never bought one, and have been kicking myself ever since. Also had a chance to buy an empty can of Zyclon B, but was just too creeped out by it. Instead I have literally a ton of WWII radio gear. Mostly RCA AR-88's, but I also have a few Wireless set 19's, PRC-6's, and a receiver from a Mosquito bomber.
