Offering this nice clean 7" long wing divider marked "P.S.&W. 7" on the side of one leg. The letters stand for PECK, STOW, AND WILCOX, the same company that had the trade mark "PEXTO" that they marked on some smaller tools. This one has little wear, some light pitting noted on the legs, and has good sharp points, very good pivot joint, ready to use. Features the fine adjustment, and brass / steel pivot joint. All the screws and threads are in very good shape, including the good spring for the adjustment feature. A top quality layout tool in it's day!
