The only replica maker that I've heard of is Telstar, which sells a new color TV in a Predicta look-alike or Predicta-inspired cabinet. Look for predicta.com if you're curious.
Repro Scott radio chassis are a new one on me, although I wouldn't be surprised, given the ever-increasing value of Scotts. Charles, do you have pointer to an example?
