Featuring a TD-24 Crawler, this International Harvester thermometer is housed in a ship’s wheel outer skin. The TD-24 Crawler was produced by International Harvester from 1947 to 1963, so this thermometer dates from that time period. What makes it unique is its brass outer display of a ship’s wheel. The outer display measures 8.25 inches tall by 8.25 inches wide, with a few minor dents on the outer edges. The inside graphic is a colorful TD-24 in red, with “International Diesel” on the hood. The thermometer is working, albeit reading warmer than the actual temperature. The lens is glass, free of any chips or cracks. 21574-WTP
