I would be considered vintage too by 1973 I was legally drinking in bars
Now I don't drink at all, I quilt instead. Does this make these quilts vintage? Now the 'quilts' I made back then were not like what I do now. Back then it was mostly baby blankets and I did not even think of them as quilts. Now your machine is considered vintage. I have a couple machines that fall into this category. One of them I use all the time and I do hope this machine of yours becomes an all the time use machine too. Vintage machines are great to sew on as the are often made better than many of the machines made today. Congratulations on this one.
