DescriptionJulien Bryan - Ambulance 646 - French 75mm shell time fuse.jpg
English: Ammunition used during World War I in France. Original description
The time fuse and head of a French "75" ( inch) shell. The fuse is ignited by a cap and trigger within the fuse at the moment the shell leaves the gun. This ignites the powder, wrapped in a spiral coil running from the top of the fuse to the screw on the left. This burns until it comes to the hole punched at the second (time unit mark on the brass covering) at which the shell is to explode. Then the flame passes into the shell itself and explodes the "B. S. P." or high explosive powder by igniting the last big cap.
