I have the phone number of a guy 30 min away that has 15,000 bd ft of old growth western red cedar for sale. He claims the wood is from 400 - 500 year old trees. Supposedly the boards are 2 1/2" thick, 5" - 12" wide, and 18' long. All this cedar was rescued from Apple/Vinegar vats from Bentonville, AR.
I called him and left a msg as no one answered. He claims some guitars have been built from this wood that sound great........though he isn't marketing it as tone wood.
Be interesting to see what he has. Here is a pic of one of the apple vats the wood is from:
