The first version, sourced to the US Navy, has a yellow or buff funnel with three white bands separated by equal widths of the ground; a blue O just touches the outer bands. Its white flag has two yellow horizontal bands, narrow outer white bands and a blue O reaching the outer upper and lower edges of the yellow bands. Brown’s second version gives the funnel a black top and three much narrower white bands separated more widely, overlaid by a blue O. Its flag is white with two yellow horizontal bands and an overall blue O.
