Hello all, looking to have HO scale decals made for the early DS paint scheme. To my knowledge these are not available commercialy. So I have a few assumptions and a few questions for the group to help get things right.

-When the medialian changed from 54" to 30" in 1945, it appears the change also incorporated the post-war medialian. Is this correct? Or was there a 54" post war and vice versa?

-Road name, cab side numbers, and hood end numbers were all 9" tall. Cab end numbers, numbers under folding gangways, and sub-road initials were all 4" tall. Correct?

-Unsure how wide the frame and hood stripes are. Thinking 4" for the frame and 2" for the hood stripes?

-Alco and Baldwin switchers had small numberboards, how tall and wide were these?

-Finally it seems all the lettering and stripes were done in silver/aluminum paint. While the lighted number boards and 2" end stripes (1945+) were in white. Is this correct?

Thanks all, look forward to the responses.
