There is no air to clear, Dave. 
It's all public domain, it doesn't matter who makes what. Wolfgang sold the design to MK. It was all wood at first. That left it wide open to copy in fibreglass by anyone. 5 or more U. S. outfits made one through the 80's with various names, so all of them were bootlegs if one was. Anyone that says they have "permission" is pulling your leg. Don ran it by his lawyer, it's a non-issue.
I know you usually build old kits and restore old models, the Tucson guy was referring to Don's mention of his own kit of the Arrow which is a splash off of another kit from the 80's outfit long defunct. I buy from Don because he's local and a friend, but I think his stuff is tops and he is swamped with orders because he produces.
