Thanks guys. Yes, I found that table of colours and their corresponding numbers too...and i completely agree that it all seems way more complicated than is necessary!
There are a few pictures of Jeeps and other equipment such as personal trunks and chests and duffel bags with these markings on, but to my knowledge nothing showing a Sherman with similar markings?
If modeling a D-Day Sherman, I'm curious as to how prominent the ETO POM marking was considering we never see them in photos?
The instructions above say the stripes were approximately four inches long and one inch wide...making the stripes marking around 3mm square in 1:35th scale?
