Can anybody tell me what color the soviets painted there lend lease vehicles. I doing a build for the m17 mgmc and need the color for paint?

They usually left them in the color they arrived in. In other words, the U.S. stuff stayed in O.D. green and the British vehicles stayed in the green or brown (khaki drab) depending on when it was shipped. I think there is an article on what the Brit colors were and when they were used on the Allied forum of Missing Lynx.
