No 7 Mk1 Dingbat mine

The No 7 Mk 1 Dingbat mine is a U.K. anti-personnel blast mine. The mine has a steel body, with a flexible pressure pad on the top surface. Under the pressure pad is a belleville spring with a central striker. The fuse is slid into the side of the mine, a firing pin prevents the fuse being fully inserted until it is removed. The mine was intended to be scattered mechanically, and a number of systems were tested to scatter it. However, none were accepted into service, so the Dingbat mine was hand laid instead. The mine came with a small fabric cover to help hide it.

Note: the United Kingdom has claimed to have destroyed all its stocks of anti-personnel mines.
