Stamped No. 104 in the brass top plate, this is the 16-inch `Sweetheart' model manufactured by Stanley and verified by the familiar SW enclosed in a heart-shape. Still carries a recognizable Stanley label (see photo).
Made in USA. But only one working bubble. The vertical glass vial is broken. Brass mountings recently cleaned and polished. Grooved finger grips on both sides. Mahogany. Some nicks and dents. Old paint and debris have been removed. Belonged to my father and used for many years as he built three houses by himself (1947, 1954, and 1969). Final markdown.
