The left shoulder strap is marked J & W Lyall New York who was the maker. The knapsack shows some wear, see pictures but for its age is in good shape. These are hard to find today, even though they were all over the place years ago. Many were destroyed on Bannermans island in a fire so they are tough to fine in good shape today.
