project "bastard case" !
No, the rust and old paint are a bit to perfect.
If you look closely at the little bit of rust below the G on the G33 code, that rust is not consistent with horizontal rusting.
The sealer that you can see, where the paint has chipped off, is a very close approximation to the factory stuff but I believe it is at least a half shade off.
The ridge around the left screw hole shows incorrect paint depth, again very close, but about just a touch overdone.
The rust spot above the Y on the Y05 code is consistent with vertical rust development, this reinforces my earlier theory related to the G33 code.
