For many years, Philips couldn’t use its name in USA because of the similarity to Philco. So in USA, Philips products were sold under various other names: Magnavox, Norelco, and probably a few more.
In the case of Mullard, originally a British company, Philips partnered with them in 1923 and then completely bought them in 1927, but continued to use the name until 1988. It wouldn’t surprise me if the same radio was sold in USA under a third name.
