Vintage Newton Tin Advertising Fahrenheit and Centigrade Thermometer, NEWTON MFG. CO., Newton, Iowa, Promotional Advertising Since 1909, #100. Works. I believe this piece is actually advertising the maker of the thermometer. Thirteen inches tall.
The thermometer works, but the sliders don't, they are stuck and I didn't try to move them.
Have similar thermometer by this maker listed for Binkley Co., Oklahoma City.
