If you're referring to companies like Matsumoku in Japan, and Peerless (Ithink) in China, then the only ones I can think of who might
qualify are Mighty Mite and Warmoth. They make authorized parts
, but whole basses to be sold under another name? Can't think of anybody. There used to be companies in Europe, as well, who made stuff for sale under other names in the '60s; don't think anyone there does it any more, though.
