This is a vintage pair of US Army Military OG Field Trousers M51 Cargo Pants, made in the United States. The pants are from the Korea (1950-53) conflict and are original, not reproductions. They are made for collectors of militaria and those interested in the history of the US Army.
The pants are in good shape and have been well-preserved over the years. They are a great addition to any collection of original period items.
