Where's the wear? I can see a touch around the 4000 insert, I think.
I think that is dirt on the glass that has shadowed onto the playfield.
The playfield has alot of crazing and ball swirl marks but it looks like there is a coat of clear over the playfield now which is giving it the nice shiny look. There is a bit of wear on the top side of the pop bumpers as well. It could be worse but it could be better as well.
Ah, should have looked at the photobucket photos first - I see what you mean now.
