Speaking of spares, when I was a dealer Snap-on had a very good parts department, and a very extensive list of replacement parts. It might be fun to get on a Snap-on truck and have a look in the parts book and see if parts are still available for those balancers. If so, one could build a new one. There can't be more that tow dozen parts in one of those things, plus the cones. The bearings are probably the same as in an alternator. Pretty simple devices.
The cones and shaft would be the most important parts as they must be as close to perfect as they can be.
