Eagle Scout hat pins were produced from 1921 through 1958 with several variations.<ref name=murray/> Eagle Scouts who earned additional merit badges were recognized using Eagle Palms, introduced in 1927. Adults who had earned Eagle Scout began to be recognized in 1934 with a red, white and blue ribbon bar. In 1940, a small eagle pin was added to the bar. Ribbon bars were replaced by embroidered square knot patches in 1947.<ref name=Crowl/> Over the years, the knot was produced with various background colors to match the different uniforms. Although the Venturing and Sea Scout programs use different uniform shirts, the current knot is available only with a tan background that matches the Scouts BSA uniform.<ref name=square/> When the [[Distinguished Eagle Scout Award]] (DESA) was created in 1969,<ref name=DESAlist/> a gold-colored eagle device was introduced for wear on the Eagle Scout square knot. The Eagle Scout Mentor pin was introduced in early 2004 in a gold-colored version. In early 2006 it was changed to a silver-colored antique finish to match the mother and father pins but in 2007 was changed back to gold-colored. In 2008, the National Eagle Scout Association (NESA) introduced a knot recognizing those Eagle Scouts who are life members of NESA; it uses the standard knot emblem with a silver border.<ref name=Crowl/>
