Condition
Very good condition. The backlit plastic display is tested, working. There are two cracks extending from the left and right lower edge of the back plate. The lower edge of the plastic has melted from the heat of the light bulb. All surfaces of TOC thermometers retain excellent colour and gloss with minor stains and surface nicks. The easel on Ox Head example is creased. Each read with varying degrees of accuracy.
