I could use electrolysis on it, i don't think it is worth much, couldn't hurt.

My dad has keys like that on the outdoor water spigots on his office building. I guess they would be used where you don't want just anyone turning on the water and leaving it running. The spigot would have a square valve on it and that key would be used to turn it on and off.
That one might be a bit older and a little more stylized, perhaps because it was used around a residential building. My dad's is a little more simple and basic but the same size and otherwise identical.
This is more like the one that my dad had. I recall as a kid the ones he had were a little more ornate or elaborate, more similar to the one that you have. They would tend to get lost though and he had to replace them at one point as people were chewing up the valve by using pliers and wrenches. If I searched around the building with my detector, I would probably find the old ones if not for the fact that there are paving stones all over now days. They just put in a new patio on the back of the building and the parking lot was extended up to the sides of the building.
Nice Find BTW,Jank. I am going to jump in here and say it looks like a key from a free-standing gas heater. The reason I dont think it is a clock key or skate key is ,it appears to be cast metal and and not finished like one would expect. I seem to notice some rough flashing around the edges. HH
Hi All, What you have there is a valve key that could be used for a variety of shutoffs. From what I have seen they were used for gas as well as steam shutoffs. ( The old cast iron in room radiators) They were of cast iron or brass construction and were quite substantial as you had to turn these older valves very hard sometimes to get them to work. I included a picture of three of these valve keys I have had around the house for reference..
Clock keys usually were made of brass and were more lightly built. The chuck ends were also smaller. A clock was usually a smaller and more well made device not needing such a large heavy key for winding it. Hope this helps.. MidnightGuy
Not trying to be funny but it looks like a key that may have been for a clock, a radiator, a water spicket, or any other thing that square holed keys fit.
I think you'll all have to agree to disagree until an exact match is found... IMO
