This shell, which is of unique design, was recovered without the fuze and consists of a solid drawn steel body with a hemispherical base. A driving band is fitted into a groove near the base. Immediately below the band, on the inside of the body, an aluminium ring is secured in a groove. The nose of the shell is fitted with a ring which is secured in the shell by four indents. The ring is threaded to take the fuze.
