What would have caused the damage to the rear rolls on the Case?

Those Case Roller engines were convertible for traction use and those depressions are fillers in the holes for the traction spikes. That Robinson engine is a very rare unit indeed, only a couple of them left and I believe this is the only one in operating condition.
