I stumbled upon the "IPMS Color Cross-Reference Guide" by David H. Klaus with the Appendix FS 595a colors matched to model paints and International colors, etc. There are matches for 63 countries. Paperback 8." x 11" and 168 pages. This was listed as "Stirring the Pot Series No. 1. It's from 1988. Is there any current version of this? Is there any value for this book? I assume the WWI & WWII color matching would remain valid.
