The Argentine joint venture used two pennants, the upper blue with white F at the hoist, the lower red with a white Maltese cross at the hoist. They derive from the constituent companies’ flags. Harnack’s 1959 fleet list still shows this version.
The National Maritime Museum dates its double-pennant specimen to 1951; each pennant measures 914.4 by 2641.6 mm.
Furness-Houlder Argentine Lines was a joint venture with Houlder Brothers, dated 1914 or 1915. Rosanoski suggests that full acquisition of Houlder in 1968 marked its end.
