Ofenfabrik E. Henn

This furnace is more than 100 years old. I couldn't find any current record of the company that made it. Only historical data.
The "Ofenfabrik E. Henn" (furnace factory) in Kaiserslautern was, 120 years ago, said to be the best manufacturer of furnaces for schools and synagogues. I found this information in an article in the weekly magazine "Der Israelit" of 3rd November 1902. It could heat a big room in little time, spreading the heat equally, and still using little fuel (coal).
The furnace has number 50 on it, I guess that was the model number.
Thanks to Marlieske for hosting the derelict sunday challenge.
