Keep it for Display!!!
Marie, I HAVE to agree with Pete and Terry!! You have SUCH a unique machine, and once it's used, IT'S USED!! If you love that or a similar model, I would acquire one (certainly not difficult) and use that rather than your pristine one. In fact, it would be great to have a 'daily driver' of the same model (converted, if you wish) and be able to show people "What it looked like 52 years ago.")
