Yes.If you look at all the Limelights on his website they are nearly all tarnished to some degree.
You can try and ask him to leave it alone, but replicating old and vintage guitars is what he does. Including simulated wear.
He quoted me 12 weeks for this one, but as he was waiting for parts for other builds he did mine and finished it ahead of schedule.
Well done on oredering your Limelight, what did you go for?
