No, they're not foobies. I think Pilsbury's PS 4427s were leasers and wore TLDX markings. I don't know about the paint-out SOO cars or the MT model (not sure about car type foobie status or markings on that one). I'll try to find the article on 4427s I have and check the Pilsbury cars, later. A fair amount of private paint scheme 4427s wore TLDX markings.
