The Naval Reserve Flag.—This flag is a “swallow-tailed” pennant of blue bunting bearing a design in the center consisting of two crossed anchors surcharged by a shield of the United States and surmounted by a spread eagle, the design being in white, the thirteen stars on the shield being blue and the bars on the shield being alternate white and red. This flag may be flown as an insignia on private vessels or vessels of the merchant service commanded by officers of the Naval Reserve Force, but shall not be flown in lieu of the national ensign.

It has a blue field with a yellow diamond in the center and a blue vertical foul anchor in the center of the diamond. These ships of the Naval Militia also fly a pennant at the mainmast, the part next the mast being white with the yellow diamond and blue foul anchor design upon it and the remainder of the pennant is divided longitudinally into two equal stripes of blue and yellow.
The Shipping Board Flag.—This flag is flown as a distinguishing flag, or “house flag,” by the merchant ships operated under the United States Shipping Board, and consists of a white flag bearing a shield of the United States in the center supported by a blue anchor with the letters “U. S. A.” above the design and the letters “S. B.” below it. The shield has a blue field with thirteen white stars and the thirteen stripes are alternate white and red.
