I know how much work went into acquiring it . . .
Because I helped: A round-trip drive of over 900 miles, cash for the dryer, along gasoline and meal expenses.
It's a 1952, but it's safe to assume that not a single member here would ever set foot in the Bush home so nobody who passes through there would likely know the difference. With all of that time, effort and expense, I think it's safe to assume the dryer would not be given away for free, so the year of manufacture is moot anyway.
