This vintage metal miniature wood stove thermometer was most likely a gift to retailers that bought/sold Cooper thermometers and thermocouples. It is in working condition. It is made of metal and painted black with gold numbering and lines marking degrees. Has a smaller circular area in center that breaks down the degrees from tenths to 2/10's. The thermometer measures 5 1/2 inches tall and 3 1/2 inches wide. It is 3/8 inches thick.
