This is a long shot, but maybe we have a Sikorsky historian in the house.
In early 1935 Sikorsky asked for information about the Dutch Navy's requirement for a new patrol flying boat for the Netherlands East Indies, which led to the Dornier Do 24, The requirement called for a 180 knots top speed, three or four engines for a total of 2000-2500 hp, and a normal take-off weight of about 10 tonnes. Supposedly Sikorsky did submit a proposal, likely something in between the S-42 and S-43, but I'd like to know more.
