The Walter Redfern Company, also called Redfern Plans, was an American aircraft manufacturer based in Post Falls, Idaho and founded by Walter "Wimpy" Redfern. The company specialized in the design and provision of plans for homebuilt aircraft, particularly replica aircraft of the First World War. Redfern's plans were adapted from the original aircraft drawings with assistance from Peter M. Bowers and Reinhold Platz, one of the original design team for the Fokker DR1. Platz continued to collaborate with Redfern until the former's death in 1966.
