(Plates X to XIV)

All types of projectiles, including mortar bombs, grenades and rockets usually have the abbrevation "Gr" or "gr" meaning Granate, or for certain non-explosive projecticles (e.g. Star) "G" or "Gs" meaning Geschoss, inlcuded in their base designation. In addition to the calibre, the abbrevation may have a prefix to indicate the type of projetile or the equip-ment in which it is used, e.g. "Sprgr" for H.E. shell, "Wgr." for Mortar, "Igr." for Infantery gun etc. A suffix consisting of numerals (Model No.) or letters or both, is included in the designation of projectiles which are different materially, ballistically or in action, from another of the same calibre, and is particularly important for identification purposes, when they closely resemble each other. The following are examples:–

A normal type of bomb with the head integral with the body.

A jumping bomb. The head which is lightly attached to the body ac-commodates an ejection charge to throw the bomb into the air after impact.

The above modified to convert it into a normal bomb to burst on impact.

In the case of some A.P. projectiles the number provides a means of distinguishing shot and shell, and whether they possess a penetrative cap when fitted with ballistic caps. For example, the following shell have the same external appearance.

Has a T.C. core and is without a penetrative cap.

The letters, which normally follow the number, indicate the character or purpose of an individual type, e.g.

In this connection too, shell of foreign origin and non-German calible have the calibre in millimeters marked on them.

The above designations are not a a general rule stencilled on the shell of "fixed" Q.F. am-munition but may be found on the base of the cartridge case and the base of separate loading shell. They will invariable be found on packages and package labels.

Further abbrevations are given in the Appendices.
