U.S. Luger Holster for The 1900 American Eagle Test Lugers. This is the scarcest and nearly impossible to find of any U.S. Military holsters! Inspected by E.B. on tongue of holster flap. U.S. cartouched. Reverse is marked “Rock Island Arsenal E.H.S.” (Inspector). You can find a test eagle, you cannot find the test eagle holster. Guaranteed genuine.
