The Compo Stapler was manufactured by the Compo Manufacturing Company located in Westport Connecticut. The patent dates back to 1923 and was invented by Richard J. Holt-Hausen. The plunger still functions...just need to find the staples for this model.
It was sold as a non clogging paper stapler. Cool collectible for your stapler collection or office.
