Unfortunately the only heller prints I have are for a m/g job, a single spped AC and a hydro. Being Westinghouse bought Heller back in the day, maybe you could try Schindler Milwaukee. Where abouts is this job located?

Your L2 going to ground is called grounded "B" phase, very common in Milwaukee. East side.
