Pernambuco Power Factory — source-chart attribution c1950

The circa-1950 chart shows a triangular flag with five vertical dark-blue and yellow stripes. Jorge Candeias suggests that the power factory may have operated its own vessels, perhaps as a foreign investment, but explicitly presents these as guesses. No funnel is shown; Rosanoski suggests that, if the State identification is correct, its sole vessel may not have had one.

No State-company equivalence or American ownership inferred.
