For sale is a Pneumatic (Air-Operated) Industrial Staple Gun. The OEM tag is missing; I believe this stapler was manufactured by Spotnails, but cannot be sure. The staple carrier magazine measures 2.035" X 0.300" thick. The lower part of the stapler's firing section is labeled "750". NOTE: I have performed a basic air-test on this stapler; it sounds good and fires correctly.
