This is a classic H Disston & Sons handsaw No. 12. From my research, it dates from the 1920s. It is missing two screws, including the medallion. The handle has a crack at the bottom and one of the horns has a part chipped away. Otherwise, the saw is in decent condition for its age. It has an unusually narrow blade with a cutaway at the end. The blade is 26" long with 7 tpi.
