Does anyone know if Opalescent Gunmetal could be ordered from the factory for a Series 1, 4.2 liter FHC? I'm thinking that availability ended with the 3.8 liter car, and was possibly replaced with Opalescent Silver-Grey. I'm not sure, as I've read evidence both ways. I know that there are some 4.2 liter cars that are now Opalescent Gunmetal, but I don't know if that was available from the factory at that time the car was built. Thank you.
