CHRISTIAN F. AHRENKIEL GMBH & CO.

Stewart’s A170 and Maritime News’ A171 have larger cantons than other sources; Rosanoski uses Nüsse’s A170 version. Mobil gives a buff funnel base for A171, which correspondence dates to adoption in 1969. New Zealand Orient Lines used the livery. One Wellington sighting is written “14.5.1007” in the original; a separate passage gives a 14 May 1997 observation of NZOL Campaigner.

A172 follows the starboard funnel colour of NZOL Campaigner on 14 May 1997 and a flapping flag described as Ahrenkiel livery, with further colour confirmation from Edward’s Photo Site. Schneider records two flag portrayals: blue with the white fish-and-oak-wreath emblem, and a red canton containing a white masoned Hamburg gate. The flag seen above the company building in December 2007 has the gate bounded by lines on either side; the image seen at the door on 18 August 2008 uses curved boundaries like the city flag. The 2007 version is also illustrated in Carsten Prange’s Hamburg history.
