Was the COBRA lettering polished on the small letter S1MS intakes? I'm currently restoring all of the aluminum pieces on a '65 in the SMFS200 range, which appear to be original to the car. The letters have a surface that does not look like it has been polished, but seem to have a similar surface profile to the surrounding areas, certainly different from the fins and letters on the valve covers and oil pan which have obviously been through a polishing process. Obviously I want to make sure that I get it right. Thanks.
