Nice find!
That mixer is almost exactly like the one my mother had. The only difference was that hers was blue, not white. I think she got it in the 60s. That mixer was used pretty regularly--we had no stand mixer or food processor--and it lasted until the late 80s. It stopped working--no idea why--and my mother went to Fred Meyer and got a new mixer. The cheapest they had at $13 if I recall right. 13 is at least symbolically a good number for that replacement mixer--everyone who used it hated it. It had no power compared to the GE, it was noisy running, and it didn't even live long enough to see its second birthday. At least, it gave a good lesson about the value of buying quality.
Today, I have one hand mixer--a fairly modern Krups. It strikes me as decent, although I'm not sure if when (if ever!) I last used it. Although that's less about the mixer than the nature of my cooking these days--about the only mixer task I ever have is bread dough, which automatically goes to the KitchenAid stand mixer. Years back, though, when I did more cooking, I considered a hand mixer well worth having, even with a KitchenAid stand mixer.
