From Richard Leonards NYC Collection: What is notable here, however, is that some of the nonstreamlined J-3s came with Scullin disc drivers like the last five streamlined "Twentieth Century" Hudsons of 1938. After the Scullin drivers had been found to be developing cracks in sustained high-speed service, most were replaced by the Boxpok (box-spoke) type by the end of steam. Photos exist of NYC Hudsons with a mixture of the two types.

I'm going for the all boxpok model. My railroad can't afford to have wheel failures.
