This tool restoration is on a model 27BC Acme Staple Co. stapler. The Acme Staple Co. is actually still in business today. This particular stapler is somewhat difficult to date as the aluminum castings contain reference to the Camden N.J. location where Acme Staple Co. was based out of from 1909-1959, but the metal label references the Franklin, N.H location where the company was based out of after 1959. I am going to assume this stapler was made around the time of the transition between the two locations. The first design for this type of stapler was patented in 1934 and can be seen here: https://patents.google.com/patent/US2... The restoration on this tool was fairly straight forward as no painting needed to be done. After disassembly all steel parts were de-rusted and the aluminum parts were sandblasted and then tumbled with fine media for a few hours to smooth out the look. The only stock removal I did was to smooth out any large dents or scratches on the aluminum parts that may have accumulated during years of use. The stapler came with a few copper staples in it, so I was able to test it out once put back together. It's definitely a heavy duty stapler and I can see it being used to staple thin wood boxes together in the 1960s.
