It is NOT a 2 piece lamp! The Oil Fill Collar and Cap are set nearly level on the new lamps, the top is tapered slightly with a pronounced rise in the glass at the oil fill of the original lamps.
Meaning that it is an Original 1940's lamp. It has an ORIGINAL #501-9 Aladdin Glass Shade with 10 Panels in the Dome and has wheel-cut top and bottom edges. I took pictures of all four sides so you could get a good look at it.
This is a WORKING KEROSENE LAMP, the font holds oil, the font cap unscrews easily, the burner unscrews easily, the wick riser turns and the wick goes up and down easily. The wick is already in it and it looks like it has been used. This lamp is in excellent condition, no chips, cracks or fleabites on any of the glass parts. The total height of this wonderful lamp is approx= 25¼ tall. The Lamp is=10½ tall to the base of the collar.
The Shade is= 8" tall X 11¼" wide with a 10 wide bottom fitter. The LOX-ON Chimney is= 12½" tall with a 2? This lamp would be an excellent addition to any home, Victorian or Modern.A Great OIL LAMP to have when the lights go out!!
