Excellent work, Ron. Having just went through my 6S152 back in August, the "drill" looks very familiar. Regarding the chassis, originally they were copper flashed I think, and later on they were painted, so there's not much that can be done other than stripping it down and have it re-flashed, or mask it off and paint it. I opted for the latter on most of the Zenith's I've done. I've used both of these paints....some of the Zenith's had a more "hammered" appearance to the paint, while others were just plain copper. You can find this paint at Menards, Home Depot, even some auto parts store chains carry it.

   

Good idea taking photos of how those dial glass clips go in. They take some finagling to get out...even more so to get back in! Thankfully the following year they stopped using those easily lost clips.
