1910S Altitude Gauge, Early Ashcroft American Radiator Company, New York, Vintage Industrial Factory Salvage

Nice antique gauge, with a scale up to 30, probably from the 1910s, with a needle shape typical of the Art Deco period. This is one of the oldest gauges I've discovered, & very neat as it is the first gauge I've found with an expansion bulb still attached. Marked "American Radiator Company", this was made by the Ashcroft Manufacturing Company of New York. There is a patent date of 1910, so I suspect the gauge would have been made some time during the 1910s. The gauge measures about 4 5/8" in diameter, the gauge body is about 1 5/8" thick ,and the connector adds another 4 1/8". in decent condition, with lots of flaking paint, minor dings & dents & general wear & tear. Remarkable that the glass is intact. It weighs about 2 1/2 pounds. FREE shipping within the United States. I'll gladly combine shipping with other items whenever possible.
