Brown 1929 and 1934 give a blue flag with a yellow frame enclosing the diamond and its cross paty. The 1929 change from border to frame is not entirely clear; its funnel also appears to have a very narrow upper yellow band and a broader lower band. Rosanoski allowed for apparent printing mishaps in drawing the version, which Brown 1934 supports. The 1929 caption is Rederi Bore Cordelia; the 1934 edition omits the name and gives only the operator.
Do not assert Bore and Cordelia were one legal entity; printing reconstruction qualified.
