This spirit-filled thermometer was manufactured by A J Dodge of Peterborough, New Hampshire.  It has a 7 inch tube and the scale ranges from -40 to 125 Fahrenheit.  The housing and base plate are very light-weight sheet metal. ​ I don't know when it was made, but A J Dodge was in business from about 1900 to 1933.  If anyone has more information on A J Dodge or this thermometer, please contact me.
