carter carb colors

after posting the thread I found this: " In general, finishes on Carter carburetors were for metal protection, not appearance. Notable exceptions would be the WD-0 carbs used on the V-16 Cadillac, and the YH carb used on the turbo Corvair, both of which had black paint applied over the normal body finish, and chrome steel linkages. Carter Carburetor Company was located across the street from Crown Plating. Carter had an anti-corrosion specification for steel pieces which would have been met by using any of the following electroplatings: white zinc, white cadmium, yellow zinc or yellow cadmium. As the steel pieces would arrive at the plant from the stampings plant, they would be sent across the street to Crown, and electroplated with whichever of the 4 finishes Crown was running that day. Since Crown ran more white zinc that anything, more of the Carter steel pieces are plated with white zinc than the other finishes. However, I have seen new Carter carburetors, which had steel pieces representing all four of these finishes. Carter used the chromate finish on zinc allow, aluminum was left natural, and cast iron was “iron phosphated”, and then painted with a “special” body paint. Mostly, this paint was black (about 60 percent gloss), but brown and gray were used on certain carburetors." From the Carburetor Shop finishs. Interesting.
