Antique Electric Heat Regulator Co. Minneapolis Minn Thermostat C1907 W Clock

Description

For sale is an antique bronze/metal heat regulator with clock (parts) that was made around 1907 - see below. The thermometer is not cracked, and it works as well as the temperature control knob. See photos. The switch is about 10" long and about 1 5/8" tall. On the top it has "ELECTRIC HEAT REGULATOR CO, MINNEAPOLIS MINN" and on the side it has "SOLD BY SYRACUSE NEW YORK BRANCH, FRANK SPRAGUE, MANAGER", and on the bottom where the clock would be attached it has "PAT PENDING".  The clock is included, but as you can see the spring is sprung, and the housing is missing. On the clock face it has "MINNEAPOLIS HEAT REGULATOR, MINNEAPOLIS". Very interesting early thermostat. It looks like it is made of bronze, but I'm not sure. See photos for condition/description. Maybe a STEAMPUNK repurpose type item? As it states below, the patented in 1907, and this one that is for sale predates 1907 with PAT PENDING. Ships USPS Priority or eBay Global.
From the National Museum Of History - THE MINNEAPOLIS THERMOSTAT web page:
This is “The Minneapolis” heat regulator that was manufactured by the Minneapolis Heat Regulator Company of Minneapolis, Minnesota in 1918. The Minneapolis model was first manufactured around 1907, when it was first patented, and the time attachment seen in this object was sold with the Minneapolis beginning in 1912. The Minneapolis regulator had a thermometer that displayed the temperature in the room, a thermostat that kept that house at an even temperature, and a time attachment that could be set to turn on the furnace when desired. A key would be used to wind the clock, a necessary feature for the clocks that were not powered by a battery or hard wired into the house’s electrical system. The Minneapolis Heat Regulator Company merged with the Honeywell Heating Specialties in 1927 to become the Minneapolis-Honeywell Heat Regulator Company.
