Hello, I have a question about the original paint on the R-390 non A. I have a R-391 that I'm working on, the colors should be the same as the R-390? Are the top and bottom covers suppose to be painted the same gray color as the sides or should they be the gold anodized color as on the R-390A? Thank you in advance for any help. Best, DW Holtman WB7SSN
