I subscribe to a number of rather eclectic military history publications to include Warship International (which I plug on Warship Wednesday) as well as Military Historian and Collector (the journal of the Company of Military Historians). One that I don’t plug enough is The Artilleryman, which covers all things that go boom, basically.
This is John Bartleson Jr.’s article from the Summer 2016 “The Artilleryman” Magazine. He details the Sawyer percussion fuse.
Text and illustrations by John D. Bartleson Jr., author and illustrator of the 1972 field guide for Explosive Ordnance Disposal (EOD) personnel titled “Civil War Explosive Ordnance 1861-1865” with radiographs. He is a retired Explosive Ordnance Disposal technician, retiring with 30 years as a CWO4, USN.
By all means check it out The Artilleryman, now in its 37th year.
