Circa 1850s
New England glass possibly. 
Does have 2 hair line cracks that seems to be on the inside , you cannot feel them on the outside as this globe is so thick.
Weighing almost 4lbs , very heavy little lantern. 
Bayonet fount with solid pewter whale oil burner .
No cracks in the brass.
Price reflects the as is condition,  rare piece,  that still displays beautifully.
