This restoration is on a 1920s Hobart coffee grinder that I recently found at auction. You can see the patent for this tool here: https://patents.google.com/patent/US1... The smell of ~100 year-old coffee is now something I can never forget. The coffee bin was missing so I ordered a replacement off another Hobart grinder. The hopper was significantly dented and may not be original to the machine. The tool was also coated in over 7000 layers of paint for some reason. The burr disks were in excellent condition and seems to be made of some of the earliest stainless steel I have come across so far.
