That's an old a new MTO coin.
Well just like the subject says I was wondering if you guys can look at something and give it a thought? Somebody found something and I’ve been going nuts trying to figure out what it is because I think it is way cool, I think it would be a cool like edc or pendent of some sort, but I just can’t figure out what it is? The closest thing I can figure is a old radiator valve, but the directions would be wrong,, who knows it might not even be plumbing related? It just looks like it goes on a valve? I’m just curious? Any ideas?JR Here’s a pic of the object and the closest thing I could figure,,
Given the square drive in the centre and the milling on the edge and the inscription I'd be pretty sure it is an actual control knob for something related to heating ( or cooling ? ). The reverse direction of rotation might hint at something that is primarily for cooling (although I'd expect to see "Warmer" rather than "Hotter" if that was the case), or maybe it is just for a heating valve that operates in the opposite direction to most.
It's probably from a water heater. It controls the flow of water. More water, cooler, less water, hotter.
