The flag is red with a white diamond, containing an upright blue anchor without rope and blue S and A to either side of the stock. Rosanoski corrects the claim that the diamond’s points reach the flag edges. Larousse and Talbot-Booth 1936 wrongly assign it to Compañia Sud-Americana de Vapores; Talbot-Booth corrected the entry in 1937.
The 1925 Almanacco gives black rather than blue charges.
