Les Jensen, Curator of The Old Guard Museum in Ft. Myer, Virginia says, "The Federal Issue Trowsers pattern...is the first that has been based on solid research; both in archival records and using original garments...I only wish this kind of thing had been available when we were starting out."
The pattern includes extensive historical notes.
