This is for a 1940's MASON ROOTBEER Metal Thermometer. It is a Working Thermometer, but it has a few flaws. It is faded a little and it has a scar/ scratch / dent right about the middle of the bottle. It is an all Original Thermometer.
On the back of it is a piece of tape with a note written on it of where the gentleman bought it from and when and how much he paid for it. Please look at the pics.
