Solid cam damage diagnosis help

I wasn't looking for a freebie. I want to learn from the situation. I had already ordered the replacement cam. I just called once again and spoke to Tim. He did glance at the pictures and was referring the situation to their cam tech. I was very upfront with him this morning of the situation. Like I said I want to learn and correct the situation. I hope they are equally forthcoming if it's determined it a bad grind. I just want to know. I am really going to try and locate a lathe to check the taper.
