These photos are taken of a bomb from Phil Eledge's (phil-at-xesi.com)
Phil's comments: I have attached a
folder of pictures of a piece of ordnance of mine. I was EOD in the
US ARMY for 7 years and this piece was from a call that had two "Mills
Bomb" grenades and this item. We were told by the police who seized
this that it was a "WWI hand dropped bomb". This was what the family
called it. We took the items because we could not identify if they
had explosive residues still in them at the time. This piece is fully
inert. Being an ordnance guy I have came up with a solution for
explaining the function of the fuzing and use. Tell me what you
The pilot of a bomber would have a stack of these to the right or left
of them in the cockpit. They would have a tube to drop these down
between their legs. The tube is just slightly larger diameter than
the safety pin on the back of the fuze. The fuze has two bore riding
pins released from spring pressure. These are released when the
safety pin is pulled out from the back of the fuze. When the bomb
clears the tube the bore riding pins are free to fall away allowing
the firing pin to function. The fuze functions from any angle when it
strikes the target due to the two cupped parts of the fuze holding the
steel ball. The cups separate and the firing pin hits the detonator.
So this is a, "all ways acting fuze". The markings are clear in the
picture. The fuze components are brass or copper, the main body of
the fuze is possible nickel and the body is steel.
Thanks for any support. I would like to know if there might be more
The following are the "three standard US Air Service HE demolition bombs, the
22-lb Mk II, the 50-lb Mk III, and the 260-lb Mk IV. The Mk IV normally had a
suspension lug screwed into its nose for vertical carriage.
About 6 months ago I spoke to you about this bomb I have had for 48 years. I
finally got to cleaning it up. Under the rust and paint was a U. S. A. Navy
Blue. I knew it was of WW1 vintage. I know nothing more. Perhaps you can fill
me in on it.
