OK that is probably ww1 Spiniker white. Nearly the same mix as todays Alpine white. That's the color choosen for my 67 ragtop project. Same color convertible top in shiny vynil is here. Car will look more like a notchback when the top is up. Looks great beside the metallic red vynil interior too. Even have the red boot so when the top is down there's red fish guts from end to end.
