A student of early historical kites, Jan Westerink of Zutphen, Holland, was searching patent databases when he found a design by Matthew B. Sellers, an American flight pioneer, that caught his fancy. The kite has wings like a glider and an eye-catching tubular tail. It was patented in 1908, meaning its 100th anniversary was due this year. Westerink, a former industrial designer turned handicraft teacher who has built replicas of several dozen largely unknown kites from the first half of the last century, decided to build this one.
