The Gatling gun...

The ARMY & NAVY JOURNAL, New York, April 9, 1887 Subtitled: "A Gazette of The Regular and Volunteer Forces." See the photo below for the terrific & quite large illustrated ad for "THE GATLING GUN" with some details. Loads of military news and ads throughout. You get the complete 20 page issue, which is in relatively good condition.  However, a tear measuring approximately 2.5 inches can be found on each page.
