vintage malt mixer glass, stainless steel replacement / extra mixing cup

USA made stainless steel cup for milkshake / malted mixer. This isn't marked with a brand, though it looks like it's made to fit a Hamilton Beach malt mixer. It's 3 5/8" across the rim of the cup, about 7" tall. It's clean but does have scratching from use.
