Copper Hanging Lantern - Bryant

I have this neat copper hanging lantern, the only name I find is inside the bulb socket it says Bryant. Not finding anything like this, though I have found some electrical parts marked Bryant. 5" diameter 9 1/2" high. Thanks again!

 

Bryant is an older brand going back 120 years. The riveted construction is nice. The glass looks amber tinted which is seen more often in the 1950's-60's. A close look at electric parts (if original) can pinpoint age within 10-15 years.

 

Thank you. No electrical parts except for the socket.
