Possibly mid 1880’s although in they were in production as late as the 1920s. The instrument is fully functional. It is secured with one hand and the vibrating plate placed over the desired body part. Turning the handle with the other hand produces a surprizingly intense vibration over the affected area. It comes with a full complement of paperwork (16 and 58 page booklets and a pamphlet) all in excellent condition.
