Help! Mystery Motor

I purchased a box of miscellaneous electrical parts at a swap meet. This 1250KV motor with a 9x6 prop was included in the box.


I measure it as 35mm Diameter, 43mm Long with a 5mm shaft and weighing 5 ounces. The closest motor that I can find doing an internet search is this Firepower 15 Speed which is discontinued from Heads Up RC.

Any guesses as to what this motor might be?
