Hello Richard,
Go to
www.cv-6.org. for the type of deck markings Enterprise had at that time.
Image Library-Dates-1942-April, May and June. The pictures shows three rows of stripes. The two outer rows run the lenght of the flight deck. The center ones runs between the midship elevator and the forward elevator. The stipres look like they are a foot wide, if that. In the sun the stripes have a yellow tint to them. In the shade they are a light gray/white color. The only other markings are the numbers marking of the distance to the end of the flight deck.
There is also a modeling thread on the Enterprise site that might be of help also.
When I did my "Midway" Enterprise, I maked off the stripes and painted them with a light coat of white followed by a light coat of clear yellow.
HTH
Gordon
