Sewing machine model numbers
Is there any rhyme, reason, or logic to how sewing machine models are named/numbered?
Does anyone know why Bernina would use duplicate numbers (as 820, and 830, for examples) for their machine models? It seems very confusing to me.
I know that with the Pfaff series 1471 -1473 - 1475 - the higher numbered ones have more features than the lower numbered ones.
However, on the Singer 401, 403, 404 series - the 401 is the "fancy" one and the 401 is a plain Jane straight stitching machine.
