Paint Colors and combinations

I am looking for someone that will help me with Duesenberg colors. I am not a Duesenberg owner, rather I am an avid model car builder. I build models professionally and I want to add one of these magnificent automobiles to my own collection. I am building a Duesenberg SJ Dual Cowl Phaeton and need to find out a source for the colors that were available for these cars. I have a source that will mix exact colors and prepare them for use in an airbrush, but I need the color name and/or number.
Will someone please help me provide a source for what I need?
Thanks SO much ahead of time for your help.
