These types of gas lamps would have been typically used by people inside their houses from around 1928 to 1935 and were sold in America, the UK, France, Australia and Argentina. This lamp is a table lamp but there were also one which would be hung from the ceiling. Aladdin Industries (the maker of the model 12 gas lamp) also made vase lamps which would be used as a more decorative item than the traditional table lamp.
This is a gas lamp which was made from 1928 to 1939 in the UK and is a model 12 Aladdin gas lamp. The model 12 was a completely new model from the ground up. The model 12 lamp was the first to have optional paper shades as well as glass shades. The model 12 brought decorative glass shades into common usage.
The model 12 burner stayed in production until the early 1950’s to repair model 7 through 12 lamps for sale overseas. Aladdin Lamps were established in 1908 and are still making lamps today, now based in New Braunfels Texas
