The Curtiss HS flying boats were operated with great success by the US Navy during WWI, starting with the HS-1L. They were powered by the 330hp Navy Liberty engine (providing the "L" in the name). HS-1Ls operated out of several bases in France as well as seeing extensive use in the States.
In order to increase the bomb load, the six-foot panels were added to each wing, the rudder was enlarged, and minor changes were made, creating the HS-2L
. The HS-2L was deployed near the end of the war and it is not known whether it saw service, but it saw extensive use after the war. Most HS-1Ls were eventually converted to HS-2Ls.
This model comes in both 1:144, 1:200, and 1:285 (1:288) scales. On the 1:285 product, a propeller disk is used instead of propeller blades (which are difficult to print at small scales). By customer request, the 1:200 product includes no crew.
