Still working on my "N" scale modules and was about to add the road markings. Modeling the early 40's and I don't know what color to use for the center stripes - yellow or white. Was a little to young to drive back in the 40's but I think the center lines were all white and later, time unknown, the U.S. went to a yellow for road division. Surf'd every thing I could think of on the internet and searched some old magazines to no avail. Anyone know?
