Conversion. Flooring to gunstocks. Stocks for Army rifles. A large walnut slab, known as a flitch, is marked for the cutting out of sound planes for gunstocks. Light chalk marks indicate defects. Black marks are the outlines to which selected sections for "rifle furniture" will be cut. Because of knots, swirls, twisted grain and other faults, only a small percentage of the flitch can be used.
