One thing at a time. I decided to learn more about the Cutlas hubs and see if they were going to work. Took them off and they were filled to the brim with nastily, dirt-contaminated grease. Somehow, my fumbling around me met with success in getting them apart. The same nylon bearing as shown in the tech tips on this site, but a completely different design (seems to be the precursor to the one shown in the second flyer in the tech tips).� Nylon bearing was in good shape as was everything else. I think that are going to work for another 50 years.
