My buddies gave me a Ray Durant acoustic for my 21st birthday in 1975. Under the metal name plate on the headstock is 'Tama' in pearl inlay.
Since others have found the names of other manufacturers under their nameplates I'm guessing that 'Ray Durant' bought up a bunch of factory seconds and rebranded them.
I furnish that as a theory. I don't buy the 'copy' theory. If you buy a knock off Guchi bag, it's branded Guchi. It won't have a 'Bags Are Us' label with a Guchi label underneath. I reckon if you cover up a prestigious label it's because something's wrong with it. Mine had lifted under the bridge, but I soon got that fixed and overall it's a nice guitar. My son has it now.
