Antique crystal radio set housed in a handcrafted wooden box. Includes antique headphones. It is likely a handmade or home-constructed unit from the early 20th century. The set includes a cat's whisker detector for tuning signals. Similar items have been historically used to receive radio broadcasts without requiring external power. Unit in excellent condition. I'm afraid I do not know how the unit works so unable to test. Free postage. Thank you for looking.
