I've seen comparables to this and so I think this is vintage from the 1930s - 1940. It is entirely clear glass. Washington Drape. Very heavy and sturdy.
Markings on lamp say "Mantle Lamp Co. Nu-Type Model B Patents Pending Made in U.S.A. Chicago, Ill"
The glass body and the chimney are fully intact. The glass chimney actually screws into the metal base. In good shape for a product this old. There is a mantle, but it it fragile and falling apart. It is almost 24 inches tall, from base to chimney top. Truly lovely.
