You're welcome. What is interesting is the idea was proven before the Wright brothers took to the air. It took one of those 'eureka' moments decades later for the concepts to be actually put to use.
The first general aviation use for winglets was on the Lear Longhorns, the -27 and 28. They were designed as testbeds but demand for them caused Learjet to rethink their position and they did sell a few. Problem was they were short legged when it came to range.
