As a November '64 child you are looking at a "J4" date code and either a Tech, Flare Tip SuperSpeed, 'Lady Gillette' or the Slim Adjustable in either the normal nickel plated form or the 'Aristocrat' gold-plated form. A lovely razor the Slim 'Aristocrat', I have one from my birth year for my son. You can see pics here - Updated 18th birthday present for my son
