Woody & Tim,
I have cleaned up those mistakes on the
Stovebolt A-D Colors Tech Tip and on my
1954 trucks website. That link that Woody has is for files on an old server that I cannot easily get access to - I'll try to correct that page or get it deleted.
I could not find a PPG (Ditzler) code for Waldorf White. Maybe Bombay Ivory is similar but who knows?
Did you try calling PPG's Color Library and asking them if they have an offset code for Waldorf White?
