Acurite Combination Candy & Deep Frying Thermometer By John L Chaney Instrument

Acurite Combination Candy & Deep Frying Thermometer By John L Chaney Instrument. Untested. Condition is used and shows wear; paint or metallic markings interior of the glass (circled in red in photos); rusting on the metal clip; based off of other similar models I’m assuming the ornamental ball on the clip is and the screw is remaining; scratching. Please see all photos. Made in the USA. It is approximately 8 3/4” long and 3/4”. Description is given to my best ability.
