Even then, I doubt if you will dispose of your old faithful. I have my mother's 1929 Singer, the one I learned to sew on. I made many outfits for myself, including my wedding dress back in 1962. After settling down in a permanent abode, my husband bought me a new Singer as a belated engagement present. I loved that machine, sewed many an outfit for our children, and even made new suits for a hard to fit man who was 6'5", had a 32" waiste, and a 36" inseam.
As time went on I bought newer machines which offered more features to employ when making clothes for my sons and daughters. One time both of my machines broke down. My home is in the top of Maine, and far away from repairmen. I must travel for several hours to get down to New Hampshire to the sewing machine service man who is very well booked. Sometimes I must wait for three weeks for my machine to even be looked at.
I took Mother's machine out of the closet. Do you think that I was able to go back to that machine after forty years? No matter what I tried I could not get back into the swing of using Old Faithful! I had become accustomed to a machine stopping when I took my foot off the "gas", but Mother's kept on going! There was no reverse. No stitch regulator. It floored me not being able to recapture the skills I once had.
That machine is kept, for sentimental reasons, and once in a while I enter it into an exhibit of machines of the past, and with it fond memories of how I once used it with ease. I am not in favor of throwing things out just because they are old and obsolete. It's akin to throwing out a much revered relative.
