Congratulations! Five dollars is quite a deal, I'm so glad it was you that found it and not some other person who just wanted a used machine to patch with.
I'm buying a house with the contents and among a ton of antiques there is a White Rotary machine. It looks more like an old Singer though and has the fancy gold and red swirly stuff all over it. I can't wait to really open up the case and look it over from top to bottom!
