Yesterday I met with Fire Chief Mike Roman and Captain Tomm Driver on restoring this 1916 Denver Quadruplex siren. This siren was purchased by the city of Grand Ledge in 1916 and placed atop the city hall building. When the fire department moved, the siren moved with them. This siren was refurbished in the late 1990's with new bearings and was used for a few years for special events. This past year, I was able to get in touch with the chief about displaying this siren, and he was thrilled with the idea of preserving this old dinosaur.
Unfortunately this siren has sat idle for at least the last decade, and she is locked up tight. Fortunately, the rotors appear undamaged and in excellent condition, and all pieces of stator have been accounted for. With the help of the fire department, we are planning to remove this siren this spring, for a full disassembly, repair, and restoration. I will continue to update this thread as the restoration progresses. but for now, enjoy these pictures, while I source a local shop capable of brazing cast iron.
