This is exactly the kind of feedback that I was hoping for Don. I collect antique cars from 1910 to 1940 and I am a stickler for going the extra mile to ensure authenticity.
This pump will be in the garage with the cars so I want it to be correct also. I like the solid colour 1929 to 1931 pump you showed although I am not familiar with the shade of green you are referring to. The second visible pump I plan on doing as Irving Primrose and I do have an almost perfect Ioka Irving Porcelain oil rack to go with it.
Now I just have to spend time on the pumps rather than the cars.
