The flag rendered by San Pavlos has uncertain shades. Rosanoski found this version only in the first edition of Stewart, including the 1953 and 1957 impressions; the revised fifth impression may have changed it, but this is not established.
Rosanoski favours the version with the usual couped Swiss cross in the canton, supported by Brown 1958, US Navy 1961 and Walter Michaels. Michaels attributes it to the 1919 Schweizer Schleppschiffahrts-Genossenschaft, while swiss-ships links it to Alpina. Rosanoski therefore suggests that Alpina inherited the original company’s flag.
Flaggen auf dem Rhein shows the red canton extending down to the top of the third blue stripe, rather than only to the bottom of the second, and lists three companies using the design.
Mitchell also attributes the S1244 funnel to Alpina as A216. His comparable Alpina version of S1371 has the broader central band coloured blue.
