Spooner's spelling individual Wiltshire resident (9)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

Aural wordplay [Spooner’s]: “Rune-maker” (spelling individual). Apart from being a type of sail on a sailing ship, ‘moonraker’ is local dialect for a native of the county of Wiltshire. This is with reference to a story of men caught raking a pond for kegs of smuggled brandy, who feigned madness to fool the revenue men, by saying they were raking out the moon. I don’t think I have come across any of this before so although I was able to guess the answer from checkers the clue had me baffled until I researched it.
