The good news is it did not shatter but broke into three mostly clean pieces. I'm thinking I'll glue it back together. Any advice would be appreciated.
What was that base filled with?

I would be tempted to drill out a good hole in the center of that chalk. Get a short stainless steel screw and put that up into the knot, then epoxy that screw and the base of the knot/rubber into the chalk. Then epoxy the shell back on the chalk.
I see the weak point of a repair being the bond between the base of the knot and the chalk. Adding a screw would give the junction some support. You could dovetail out the center drill into the chalk too, as this would provide even more support to the screw.
Removing all the chalk would make a clean reglue of the shell very hard at this point, but drilling into it in and epoxying the screw in may work.
