The Ithaca Model 5E Single-Barrel Trap (SBT) is one of the most iconic American trap guns, produced by the Ithaca Gun Company from the 1920s through the 1980s. It was designed specifically for target shooting, not general use, and is considered a high-grade example in Ithaca's trap lineup. Introduced as part of the "Knick" (Knickerbocker) series, the 5E was the top-tier single-barrel trap model, more ornate and expensive than the Grade 4E. It was built for competition, with a tight action, precise dimensions, and durable construction. The model was named after John Philip Sousa, a famous trap shooter
