Thank you, Miriam!
More questions about the history: how are the Japanese badged deluxe zig zag machines related to the singer 15 clones? I understand after WWII the Japanese started producing the clones. Then was it just a matter of the Japanese engineers continuing to innovate, which led to the Deluxe Zig Zag machines? Or were these loosely copies of other American machines? Were they produced at the same time as the clones, or were they innovations made a little later? Thank you for your wisdom!
