I would think that this dates to the late 1800's or early 1900's period. The lamp is made by THOMAS EDISON, Inc. ands says ...Permissible Electric Cap Lamp....and has the seal of The Depatment of Commerce, Ministry of Mines on it. This is obviously the battery component only and a lamp part would have been with this originally. Measures 7 3/4" x 4 3/4". A nice Mining collectible.
