Is this rotor usable?

OK...I don't own a dial caliper so this is what I did to compare one corner from the other. Feeler gauges stuck between the apex seal and the groove. I'm sure it's not as accurate as having a dial caliper. But what I was looking for was a comparison from the good end to the bad of the groove.

My old rotor I took to a machine shop and had them measure it. I don't remember the figures and can't find my notes ATM.

I'll be buying a dial caliper tomorrow. The seller seems to be annoyed that I had not measured. I'm annoyed for the obvious reasons.

As a comparison the rotor in my engine when it detonated
