Terry,
According to this post http://www.antiqueradios.com/forums/view...1&t=199506 , I believe the 42-321 chassis and the 42-PT-4 chassis are the same. If that's the case here's a dial string diagram for the 42-PT-4.

IF that's not the case I also have a hand drawn dial string diagram for a 42-322 that I restored that "might" give you some ideas if its at all similar to the 321.

Hope that helps.
