The Circa Reproductions Nieuports are a family of Canadian 7/8 scale World War I sesquiplane aircraft replicas designed by Graham Lee of Lamont, Alberta for amateur construction from plans sold by Lee's company . Leading Edge Air Foils of Peyton, Colorado at one time also made construction kits available. Lee's Nieuports were among the earliest First World War replicas available and paved the way for later companies to produce plans and kits for a great variety of warbirds.
