This restoration was on a 1920s paint sprayer made by the Crown Spray Gun MFG. Co.. Once again, there is not much information on this tool online and my access to American library sources, but from what I could find, this company began in 1913 and produced products until at least the 1950s out of their Los Angeles, California location. I picked up this paint sprayer/compressor a few years ago because its design caught my eye. It was made with two diaphragm pumps that push air into a long tube and finally out to the spray gun. You can see a version of this paint sprayer in a 1929 photoshoot here: http://digitallibrary.usc.edu/cdm/ref... I replaced all gaskets and diaphragm with oil-resistant fabric-reinforced rubber to match as close to original as possible. I left the aluminum bare as I really don't like to paint over aluminum. I had to completely remake the top tube and fasteners as they were too pitted to be salvaged. I also made sure to oil this tool like crazy during assembly. I ended up powering it with a drill as my original motor setup was making the tool spin way too fast. It seem to work, but not as well, at the lower rpm. Maybe I can actually use this to do some airbrushing on future restorations!
