No, it didn't. It turned out glass beaded, with a grainy surface finish rather than the glass-smooth die cast surface finish the pinion housing had from the factory. Ordinarily I wouldn't raise such a picky matter, but with the level of detail correctness you are requiring of each and every part of your car, it seems worth mentioning. Fortunately, the semigloss black paint which yes, would very much more than likely have covered not just the round steel field frame and round rear cover cap but also the aluminum pinion housing and the steel gear case cover and the externally-visible portion of the bakelite brush plate will hide the grainy texture while letting the casting marks show through.
