Here is Winchester-Lee Model 1895 6mm Navy Rifle serial number 18003 with bayonet and scabbard and Remington-UMC 6mm USN ammo. It was part of the second US Navy contract (serial numbers 15001-20000) inspected by Lt John N. Jordan (J.N.J as stamped on breech. Per the Winchester Repeating Fire Arms letter the serial number was applied to the on July 22, 1898; Caliber: N; received in warehouse on August 12, 1898 and shipped from warehouse on August 20, 1898; Order number 2689. It just missed the Spanish-American War but may have served during the Relief of the Foreign Legations in Peking during the Boxer Rebellion in 1900 or during the Philippine Insurrection 1899-1902. I'll have to see if I can track down the USN or USMC ship/unit which eventually received this rifle.
