This is a 1940's vintage stapler made in the USA by the Ace Fastener Company. It is made entirely of heavy steel and weighs a ton - do not drop it on your foot! It still works perfectly and is made to last another 80-ish years. They just don't build anything like this now. Guaranteed to be the steampunkiest desk accessory in your office. It's in excellent working condition, but could use a good cleaning to remove the dust and tarnish.
