I'll try to get some pictures and post them, but I can't say for sure when that'll happen. The dealer lives around 45 minutes away, so I don't know If I'll make that drive tomorrow just for pictures. When I go up there next, I'll be sure to bring the camera and take a closer look. I thought I read that no. 4's were offically adopted in 1941 but made and issued as early as 1939, but I can't back that up as solid information and I trust your information more...thanks for the input so far.
