I guess it would depend on if the Spartons still had their original filter cans, or even which production run they were, one of my Rogers sets had what I am sure was a Mallory replacement mounted in the clamp. Believe it or not the capacitor manufacturers and parts jobbers used to offer bolt in replacements for these things for a number of years after most radio manufacturers quit using them.
