A833 Factory Paint Markings

I would say that Murray made some very valid points in #9. Specifically, the painted number was Primarily for the line person. The number would likely vary as to Models A or B or others, 18 vs 23 Spline, gear ratios, and the year. Leave us not to forget an engineering change in mid-year, of even a small seal in the transmission, which could change the part number. A nearly exact transmission would have a different number. Paint color was to "Highlight" a different part. A color can be noticed without having to read it, like a number. Ever notice that distributors had different color tags? 95-100% of the marking was to make parts easier recognized to eliminate confusion at an assembly plant.
