Aladdin No. 6 Lamp with brass wall mount and pivoting arm. I'm pretty sure I was sold the wrong wick as it is very hard to adjust. And the mantel didn't survive my photographing. So, plan on buying a new wick and mantel. I'm guessing the age of this is 1915-18 based upon the date shown on the adjustment knob - but I might be completely wrong (corrections are appreciated). The chimney was made by Aladdin and is 12-5/8 inches tall. Please let me know if you have questions and I'll try to get answers for you. I'm going to package it carefully to survive the USPS delivery trip.
