Olivetti Underwood 288 adding machines

I have a few electro-mechanical Olivetti Underwood 288 adding machines that a friend rescued from a dumpster, which look like they're in great shape (possibly never used). I haven't tried plugging them in yet, and can't promise that they work If you're interested in one or all three, let me know. I can post a picture if you're interested. From the instruction card that is with them, they appear to be from about 1960. They're about the size of a desktop calculator. I'm in West Lafayette, IN, USA. They're fairly small, so I should be able to ship them anywhere in the US without much trouble. Sorry, but no international shipping.
