Boyce MotoMeter

From then through the late 1920s, the Boyce MotoMeter Company in Long Island City, New York, founded in 1912 by the German immigrant Hermann Schlaich, manufactured different models which varied in size and design.

The non-pressurized Thermosiphon cooling systems that were widely used until the 1920s led to a low boiling point.

The MotoMeter Company soon delivered these with metal dials inside that showed the maker's or dealer's logo with script printed on it.

There were also slight changes to each of the original models and new designs, and accessories such as hood ornaments, toppers, illuminating devices or locks were added to the line of meters while some others were discontinued.

[5] By 1927 the company was offering a wide variety of motometer, but the device became obsolete when dash-mounted temperature gauges appeared around 1930.
