The classifieds on this Forum are very quiet so I would not place a bet on anything coming up there soon.
In the most popular German classifieds portal, Air Nortons come up consistently (regular and F-spaced, mostly black but sometimes zebra or double cream) but Nortons have become scarce for no obvious reasons.
With "here" I meant German "Kleinanzeigen" formerly run by ebay.
At the moment there are a few, but I really like the look of that double cream neck humbucker on that specific guitar, so I hope for a double cream Air Norton F-spaced to come up.
I think I could more easily make a Norton out of an Air Norton, if I needed to, than the other way round.
