LOHMANN & RUHLAND 'MAMMUT'
Lohmann & Ruhland was located in Duesseldorf, Germany. This Mammut has a globe lift system patented by C. Seifert - Patent Number 132019. The badge has 'D.R. PATENT Nr. 132019'.
What is notable about this lantern is the Schutzmarke (trademark) which has been stamped twice on the bottom of the lantern. There are two Mammut Schutzmarkes.
The Mammut globe is very heavy and is embossed 'MAMMUT' on one side and 'D.R.G.M. *' on the other side. D.R.G.M. stands for Deutsches Reichsgebrauchsmuster; meaning protected patented design under the Reich Government.
***I do have a spare Mammut Globe which has sustained, apparently, a lot of dropping on the floor. Given how thick the glass is, it is still intact. This globe is marked 'MAMMUT' on one side and on the other side
The burner that arrived with this lantern is not the correct burner. It is a burner (wick driver) made by Thiel & Bardenheuer of Rhula who made many burners for different lantern mfgs. A burner from a Feuerhand Nr. 201 fit seats correctly.
Overall, this is a very solid and well constructed lantern and has withstood so much over all these years. This lantern does not leak nor are there any air leaks in the tubes. This might be one of those cases where the lovely orange lead paint protected the lantern from the elements.
