In October of 1901, the Springfield Arsenal received an order of 1,000 Luger pistols for testing and trials. In December of the same year, one pistol was sent to the U.S. Arsenal at Rock Island, Illinois and was used to manufacture 1,000 holsters. The holsters were completed in January of 1902. Also, of note, the U.S. traded in 50 of the aforementioned 1900 Lugers for 50 of the 1902 cartridge counters, of which, writer believes they would have continued to use this holster with. The holster is of russet leather construction with a large oval bordered "US" on the front flap, brass closure post, and the letters "H.D." stamped upside down on the bottom of the front flap. The back of the holster is stamped "ROCK ISLAND/ARSENAL/E.H.S." with brass rivets attaching the belt loop. Includes the book "U.S. Test Trials 1900 Luger" by Michael Reese II. Pictures of similar holsters are visible on pages 29, 30, and 31 of the included book.

Exceptionally fine overall. The holster has tight stitching, overall solid construction, scattered surface scuffs, clear markings, and some slight surface age stress line. There has been two copper rivets added to the top of the belt loop during the period of usage. One will look a long time to find a finer example!
