Details of George Ferree's radio

Here are some extra pictures of George B. Ferree’s radio that won’t be in the book. He built this crystal set from a German battery box during WWI (see the book for more details). I took these at the US Army Communications Electronics Museum at Fort Monmouth in 2006. The radio, along with much of the museum’s exhibits, are, for now, in storage at Fort Belvoir, Virginia.
