Maple 1/2 of an Archtop back, could likley get back and sides for a guitar of some king with flat back, Almost an inch tall, approx 91/2 inches wide and 28-29 inches long, pictures show the item boy dry and wet. ends are waxed for air drying, I've had it for eight or nine years and it came to me as part of a lot nobody had touched for years. sufficient height for Mando back as well, could use for violin /Viola but would advise against this as it has mostly Heart wood in the billet. Milling this item into a guitar back and sides is not a project for someone who is not very familiar with the milling equipment to be used and not confident of the possibility of success with said equipment
