My singer 319w has a vertical rotary bobbin underneath and my 328k has a horizontal drop in bobbin.
Yet both do double needles.
I do get the hook has to pass behind both needles, but I don't understand how the vertical vs horizontal thing matters.
Seems to me what matters is how the OEM designed it to work....
