This is my example of this lantern. The glass is marked "Chance Hysil" and the base is stamped 5 53 which I assume is the date of manufacture. There is a rectangle in the paint where the decal used to be and a few flecks of red. It has a few problems. The needle is missing from the pricker, so I have to take it apart every so often to clean the jet. It didn't come with a preheater cup, so I used a Tilley torch. It doesn't run very well. It starts to dump liquid paraffin through the burner after a few minutes of running. I think it suffers from the same problem as the Veritas 350 and "Superb" namely the mantle is too far away to keep the vapourizer hot enough to run properly, and it doesn't have a Preston ring like a Petromax to compensate. I got this photo by running it at a very low pressure, where it seems to run okay. I thought it might have been a gasoline lantern due to the lack of a preheater. However, the presence of an air-release screw suggests otherwise. The control dial acts as both a jet cleaner and a shut-off valve.
