Sounds like a Veritas Bat with a german globe. The folks at be-back-later should know a lot about the English version of the old Bat. Do a search for Bat at IGLR and you will probably find more than you want to know. Many of the German Bat lanterns burned diesel fuel. Thuringia (a state in eastern Germany) was used on products from Germany after WWI to combat negative association with Germany. The DR Patent stands for Deutsches Reich Patent. BB
