Aftermarket Mopar piece. Many times, the company Everco would provide aftermarket replacement water valves for the Fuselage cars which were metal rather than the OEM multi-color phenolic plastic. The "plastic" was perceived as such as the metal was perceived to be a better, long-term item. Either vacuum controls (as my '70 DH43N car has) or cable controls (as our '72 Newport Royal has).
