For Your Purchasing Consideration: A RARE & VINTAGE FAHRENHEIT PROBE TEMPERATURE. GAUGE.BY THE  ELECTRIC THE AUTO-LITE COMPANY OF LA CROSSE, WISCONSIN. Large Gauge! Tough Find! Measures 3 3/4' x 1 1/4". The probe is adjustable, which makes me believe this gauge is possibly manufactured for the food service industry? Not sure, appears to have a stainless steel probe. The length from the top of the gauge to the bottom of the probe is 9 3/4" inches. In close to excellent condition. Thanks for looking! Have an excellent day!
