As far as the White Long Shuttle Zigzag machine is concerned, they were also put out as a Universal and a KADZ-620. I have two of them badged “Universal” with the numbers JC34 cast into the underside of the base. The only one that I’ve messed with so far (a black one) has a broken zigzag cam in it (the only plastic in the machine). I’m not sure about the other one (a white over turquoise).
