I just got an offer to a trade for a very primitive 1922 Deforest Wireless System "Everyman" radiophone crystal receiver and I went for it. I always wanted some type of Deforest set in my collection and a small set like this is perfect. It's complete with plug-in coil and an ancient pair of Western Electric headphones in the storage slot.The set is complete and functional with a nice instruction card under the lid.
