Stamped "Made in USA". Didn't fit 8-) The central hole has two diameters of centering boss, 2 3/8" and 2 5/8", each clocked to its own bolt circle, I needed the 2 5/8" surfaces. To my surprise they were about .015" undersize. The hole was clearly punched, since it wasn't round, but how it got fifteen thou undersize baffles me. Only idea that comes to mind is that over the years the punch and die wore, either from wear or resharpening, and nobody noticed. Or, they noticed and didn't care. A few carefully counted strokes of a rasp got the fan to fit the clutch. The centering seems no worse than the blade runout so I'll try to use it. The most impressive discovery so far is the teflon valve stem packing. I bought it years ago to seal a flange on an espresso machine boiler, only to discover the bolts were merely loose. It sat in the toolbox for years until saving my bacon on this project. I'll be tempted to try it the next time there's a leaky valve or differential cover to seal.
