I have quirky 1970’s Singer that doesn’t do reverse...I can send it for the grills to learn on...
;o]
When I was in Jr High, in Home Ec, we had to learn to sew on the Singer treadle machines before we could use the new electric Singers. I was SO far ahead the rest of the class, even on a treadle, that the late Mrs Liddle gave me a D for a final grade.
By that time, I hade made a dress, two blouses, a dress and matching shirt for me and my boyfriend at the time, a skirt and another blouse.
Mrs. Liddle hated me. How DARE I, a 7th grader, do better work than she, who had had four years of college?! LOL!
