Swingline Speed Stapler No. 4

Made by Speed Products Co. in Long Island City, NY. Patented 1937. Similar but larger than Swingline Speed Stapler No. 3. First stapler to carry the Swingline name (added later, first on the front, then on the plastic cap). Also introduced bottom release mechanism to allow tacking material to a wall.
