Well since all of my sewing machines are vintage: Featherweight given to me by my parents when I was 12, Singer 403 that was my mother's, and a 15-91 on loan to me from a friend, I have to say that if I could, I would have to try to save them. 2 out of 3 would be easy. Grab the 403 machin head & throw it in a suitcase, grab the Featherweight case. The 15-91 is in a cabinet so it might be more challenging.
Oh - and the husband would be in charge of grabbing the CPU for our desktop computer. It has all of my business work files, family pictures, etc. on it.
