I did the same on my '37 wheel, JB Weld and sanding. I doubt you will find a decent one, the material they used wasn't meant to last 90 years! I used the Appliance epoxy paint, repainted it a few years ago due to wear, the first time I painted it was in 1998.

I had a '46 wheel in it for awhile when I had the '46 steering box, I wasn't sure I liked the '46 wheel so I din't repair it, but I did install a leather cover on it, more leather like then actual leather. It felt good having a littler bigger diameter to hang on to. When I sold the box and wheel, the guy wanted the cover, I should have kept it.
