Just like some companies today - the Sewing machine companies did what they could to fool the customer by making machines that had the look of a different one, or a similar Name. BTW - a machine branded as "New National" is made by New Home. And Davis sold one that was badged "Standart"
And then when the Japanese got in the business, they uses a lot of "old" sewing machines names. I had one that was a Howe and even had the same Howe emblem, but facing the other direction.
