I don't have the exhaustive, annotative, footnoted, bibliography-included treatise, but Electrolux AB of Sweden has the rights to Husqvarna and Jonsereds chain saws, as well as snatching up Pioneer/Partner, Frontier (came with P/P) & Poulan. They also have the European rights to the McCulloch name, but not in the Americas. As well, Electrolux also owns Frigidaire Home Products, and so controls the rights to Frigidaire, Roper, and a few other lesser names, as well as American yard Products, which is the latter-day name for the old Roper OPE stuff (made a lot of Sears product). Sears used to have controlling interest in the FRigidaire/Roper/AYP thing, but after they nearly went belly up, E-lux still supplies most of Sears OPE stuff.
As an aside, Electrolux had no use for the Husky motorcycle line, selling that name to Cagiva, of Italy. I have no idea about sewing machines and firearms.
