Mystery temperature dial

with the small hole maybe it was a thermometer that hung in a wood or gas oven? or on a wood stove?

The numbers around the outside are degrees Fahrenheit.

A thermometer as Tpmetal states is a good suggestion.

Industrial temperature readout from a foundry or oven. The stem for the indicator (pointer/arrow) came up through the center hole and the second hole shaped like a crescent is for calibration. You loosened a screw that held the faceplate in place that set in that hole and rotated this plate to reflect the accurate temperature in the chamber. Once the dial read correctly the screw was tightened and the dial was calibrated. Judging by the items listed I would say a small smelting or tempering furnace.
