The following markings and designations, additional to those given in Pamphlet No. 6, have been met with in the course of examining captured German ammunition:–

The letters "Vz" in the designation of ammunition of Czech origin is the abbrevation for mark or model.

The letter "S" with an oblique stroke immediately in front of the fuze number was given in Pamphelt No. 6 as an indication of a mechanical time fuze. The same marking has since been found on a time fuze of the combustion type in naval service and thus indicates a time fuze of either type.

The stamping "Fg¹" or "Fl" following an oblique stroke after the fuze number on a mecha-nical time, or time and percussion, fuze indicates the time mechanism to be the centri-fugally operated Junghans type.

This was incorrectly given in Pamphlet No. 6, as l.I.Gr.Z. May also be found as Jgr.Z.

The dimension included in the designation of spigot mortar bombs is the diameter of the bomb and is not, as in the case of British nomenclature, the diameter of the spigot of the mortar.

The following additional abbreviations in the designations marked on cases, bags and la-bels have been found:–

Indicating a small nitrocellulose powder stabilized with diphenylamine and in-cluding ethyl centralite and potassium sulphate.

Indicating a small arms, double base propellant of P.E.T.N. and nitrocellulose which includes diphenylamine, ethyl centralite and potassium sulphate.

Indicating a nitrocellulose powder including potassium nitrate and graphite.

Indicating a central supporting tube of propellant, of comparatively large di-mensions, used as a core and support in the arrangement of the propellant charge. The size (length x external diameter x internal diameter) is given in millimeters in the form "(345.14 /12)".

Indicating solid cylindrical granular propellant. The size (lenght x diameter) in millimeters is given in the form "(1,5 x 1,5)".

Indicating propellant in the form of discs of comparatively large diameter with multi perforations. The size (diameter x thickness) in millimeters is given in the form "(50 x 0,2)".

Indicating propellant in the form of small cylindrical grains. The size (length x diameter) in millimeters is given in the form "(0,8 x 0,8)".

Code letters for the identification of the shape of Digl. propellant in sectional charges of the howitzer type are met with on charge bags, labels and packages. The letters used and their significations are as follows:–

Digl. propellant in the form of flakes or perforated discs (washer form).

These letters are found adjacent to the number of the charge section on the bags (see Pamphlet No. 6, Fig. 17), in bold lettering on labels and stencilled in white on the pack-age, usually on the lid.

The letters "o.B.D.", stencilled in black on the side of the case of a fixed Q.F. round are used to indicate the absence of a decoppering agent from rounds in which this compo-nent is normally used.

Star shell painted a shade of green (lighter than the deep olive green in common use) with a yellow band above the driving band and a black tip have been met with. This may be a naval shell.

H.E. and smoke mortar bombs may be painted a deep olive green as an alternative to the dull red as given in Pamphlet No. 6.

"Deut" painted on a projectile indicates a coloured smoke round. The colour of the paint used indicates in some cases the colour of the smoke. In other cases, the colour of the smoke is marked on separately, e.g., "blau".

The red band above the driving band, referred to in Pamphlet No. 6, page 29, is also found on shell without tracers. The significance of this band is not yet apparent.

The Arabic numerals stencilled on the head of H.E. and hollow charge shell to indicate the nature of filling are also used on mortar bombs and on piercing shell. On black pierc-ing shell the stencilling is normally in red. The following additional numerals have been met with or reported:–

Indication

The letters "oM" following the numeral indicate the absence of an exploder container.

The following abbreviations are used on labels to indicate the various natures of high ex-plosives:–

Cyclonite (A numeral after the letter indicates the percentage of wax.)

P.E.T.N. (A numeral after the letter indicates the percentage of wax.)

The letters "F.E.S." stencilled in white above the driving band and, in some instances, on the base of the shell indicate the driving band to be wholly of iron.

The red stencilling "Abgebr.Ldg." on the side of a cartridge case (reffered to in Pamphlet No. 6, page 35, sub-para. (vii) indicates that the weight of the propellant charge has been reduced for use in hot climates. The standard temperature on which the reduction is based in indicated by the stencilling "Schusstafeln P.T. + 50° C.", also in red. This standard was superseded by that of 25° C.
