Don't panic my friend, somehow the name paul came into my mind. Your #138 will get which ever peg head plate you choose. Sorry about my early morning name error.
Spalting occurs as the very early stage of decay in wood. Big Leaf Maple develops these wondrous black lines and color changes. Each piece is different and a wonder of nature. When the wood is dried the decay stops. When caught early enough the wood remains strong. When French Polish is applied it becomes truly beautiful.
