Opinions on stihl cylinder please

Was cleaning up to post in sale/trade forum and seen this. All nice and smooth. It's a 064 cylinder I believe. This normal, or trash?

Is that plating wear?

I thought that at first, but if it was plating wouldnt there be an edge or flaking? I thought heat at first, but its below the intake and its the only spot with this.

It's plating wear and aluminium transfer ingrained in the cylinder, where it is isn't a problem as the rings don't pass it. It's caused by piston slap and glazing, fit a new piston and it should be fine

it's junk

I have seen worse running. Is that the intake port? seems like someone was not to fond of cleaning the air filter.

Yes it in below the intake.
