Glass Banker's Desk Lamp. There's no maker's mark. The base looks fairly recent. I have no way to know the age or origin of the shade.
My guess is someone crafted the shade and it's a unique/one-off item. The only problem I see is a hairline crack in one of the sections which I show in the pictures.I used it as a night light with a 1 watt led bulb (bulb included). The measurements are as follows. The shade is 9 1/4'' long x 6'' wide x 3 3/4'' high. It's nearly impossible to cover everything in a short description. The best source of information regarding cosmetics and condition are my photos. This item is in the category "Home & Garden\Lamps, Lighting & Ceiling Fans\Lamps". The seller is "quiet-flyer" and is located in this country: US. This item can be shipped to United States.
