Read my plugs

That is a pic of the same plug, I just turned it, to help with seeing the whole plug. I also zoomed in on it. Looking at it in hand that little knick in the electrode is very small. I didn't notice that until you pointed it out. The other plugs I was actually just looking at the colors when I pulled them. So didn't pay a whole lot of attention to those things. I should had though. Oops.

The aluminum smear is antisieze from removing it.
