Brass, triangular knapsack hook that measures 1 1/4 inches wide, by 1 1/4 inches high. The brass surface shows typical age discoloration and some green patina is visible. The hook is solid and complete. The knapsack hook was located on the knapsack's shoulder straps. This example was once part of the famous Rosensteel collection of Gettysburg relics that formed the core of the Gettysburg National Museum collection. Founded in 1921, by the Rosensteel family, this is one of the most famous collections of Civil War relics that was ever assembled. John Rosensteel, of Gettysburg, was one of the very first relic hunters of the Gettysburg battlefield, accumulating various artifacts as soon as the fighting stopped. John's nephew George continued the legacy, and opened the museum which was located across from the Gettysburg National Cemetery. This hook was recovered from Culp's Hill, one of the most prominent areas of the battlefield. The epic 3 day battle of Gettysburg was fought on July 1st, 2nd and 3rd, 1863. Ex-Horse Soldier of Gettysburg collection. Very desirable Gettysburg relic.
