If you have not tried your local PPG (ditzler) jobber, ask him (or her) to check with the Ditzler Color Library for a current mixing formula. According to old Ditzler information on paint numbers the original K-F paint code #'s they referenced were 390 for enamel or 569 for lacquer. The original Ditzler Enamel number was DQE-41042 and Lacquer number was 41042-DAL. I do not have a Ditzler page showing an actual Ditzler/PPG Aloha Green chip.
The Ditzler Color Library is the storage vault where samples of paint colors going back to the 1920's are stored. The appropriate Chip is pulled and a computer spectrometer reads the sample, producing a print-out to re-create the color using today's available mix items. The Color Library will provide this service to the Jobber at no cost to the jobber, but the mix information stays with the Jobber.
