@Clay Holly G'day Clay and welcome to the forum. It's a gravity fed lamp but don't know by who. Will you post a clearer photo of the plaque on the font. It could help someone else identify you lamp.
Hi Clay, and welcome to the forum! I think this gravity lamp should have been posted under "Gravity Lamps - all makes". No. worry, mods can fix that! As stated in the headline, this is probably a Hasag made lamp. A couple of years ago I found a Hasag patent that shows this lamp. A variation with an overhead donut tank can also be seen and was sold in Sweden as the "Autolampan". Your lamp has many similarities to the AB Lux made "Victoria" lamp, seen here in the Gravity section. /Conny
Conny, thank you. Strange that it is called a "Petroleum Glühlicht". I would have thought it is a spiritus/alcohol light.
No, a petroleum/paraffin/kerosene lamp is not so unlikely. Hasag stole many ideas from LUX in the beginning of the 20th century, and this may very well be one of them since it seems like a spitting image of the Lux Victoria Conny mentioned above. And that's a paraffin lamp. The more elaborate spiral vaporiser in that patent also give you a hint on this.
