White didn't copy anyone. They were an excellent machine company on their own dating from the late 1800s. In the 1950s, they moved their manufacturing plants to Japan - a Koyo plant in particular. Then White went out of the manufacturing side and became distributors of Whites. The plants who had manufactured for them quickly put out a number of machines under different labels - my Universal for one, probably that Dressmaker and many more similar looking machines.
With no sewing experience, I'd pay the $10 for the manual annthreecats found for you. Please do not sew on the machine without cleaning and oiling it. For me, I hope I can remember what I need from sewing on my mother's White in the 50s. If not, I'll be looking for a manual, too.
