A727 Rebuild kits redux - Rebuild kits everywhere (62-70 vs 71+)

As I was finishing up I did a bit of final clean and paint when I noticed something that I hadn't seen before.

Thought it was odd so put stone tip on my dremel and figured it wouldn't hurt to see what I see.


It appears to be a surface issue... not sure what it was. I looked on the inside it it was clear. I decided to roll with it... cleaned it up and put some paint on it



On to the next thing. :)
