Identification of the Fixed Cartridge Cases and Charges

Stenciling on Side of Case. The following details are arranged in the sequence in which the Markings are normally found between the aproximate center of the case and flange at the base. (See fig. 318.)

1. The caliber, types, and model numbers of the weapons for which the round in suitable are penciled in the form: 7.5-cm KWK 40 (7.5-cm Tank gun model 40). Where the round is suitable for more than one equipment, the designation of the equipment is stenciled in sequence with the letter "u" signifying "and" as a conjunction.

2. The weight of the propellant charge in grams stenciled in the form of numerals, follow-ed by letter "g" below the nomenclature of the ammunition (e.g. "164 g").

3. The nature, shape, and size of the propellant are stenciled below the marking indicat-ing the charge weight.

The following markings are used to indicate the nature of the propellant:

Figure 319 – Semi Fixed Cartridges Cases

These letters, in the case of double base propellant, are following by figures or letters which also appear to relate to the composition. The shape of propellant is indicated the following letters added to those used to indicate the nature:

Bl.P. – Blättchen Pulver: Flake.

Rg.P.: Perforated Disk (resembling a washer).

R.P. – Röhren Pulver: Tubular.

Str.P. – Streifen Pulver: Strip.

In the case of a double base powder the number cutside the brackets indicates the per-centage of explosive base added to nitrocellulose. The size of the propellant is given by a statement of the dimensions in milimeters following the letters used to indicate the shape. The dimension figures are enclosed in a bracket and are arranged as follows, with commans serving as decimal points:

Flake (length-breadth-thickness) (3.3.0.8).

Perforated disk (thickness, external, diameter/internal diameter) (1,9 x 15/4).

Tubular (length with minus tolerance, external diameter/internal diameter) (175-2/0,85). An "x" is sometimes used instead of the "–" between the length and the tolerance (length-breadth-thickness, e.g. (125 x 5 x 0.5).

Examples: Digl.R.P. 8, 2 (175-2, 2/0, 85). Gu.Bl.P.A.O. (4,4, 0, 6). Ngl.Bl.P. 12.5 (40 x 40 x 0,2). Nz.R.P. (135–5, 5/2). Digl.Str.P. –9.2– (125 x 5 x 0,5).

4. The place and year of manufacture of the propellant, followed by a lot number are stenciled below the marking relating to nature, shape, and size. The following is a typical example:

dbg 1942/3

5. The place and date of the filling of the propellinge charge, followed by a lot number are stenciled below the marking relating to the manufacture of the propellant:

(on 17.642 xv)

6. The red stenciling used to indicate porpellant charge of a reduced weight for hot cli-mates may be found near the base of the case, just above the flange, or higher up the side of the case, above the other stenciling. The marking used:

Tp – -25° C.

Indicates that the normal or standard charge temperature on which the weight of the charge is based is 25° C (77° F.). The German standard charge temperature for normal European temperatures is 10° C (50° F.).

7. In some instances cases are stenciled:

"Abgebr Ldg" in red.

This marking is found near the base (corresponding to the position of the Tp -25° C. marking) and probaly refers to the propelling charges of low stability which are to be gi-ven priority in expenditure.

Stenciling on the Vase of Fixed Cartridge Cases. Type of the projectile is stenciled in white or black to the left above the primer hole.

In some instances the Roman numerals indicating the weight classification of the projec-tiles are stenciled in white to the right below the primer hole.

Stampings on the Base of Fixed Cartridge Cases. Model number of case:

St. – after model numbers of case – indicates a steel case.

Model, cal., and type of weapon.

Manufacture's initial.

Delivery number.

Year of manufacture.

Markings on Cartridge Bags in Fixed Rounds. The markings are the same as those stenci-led on the side of the case except that the caliber, type and model number of the equip-ment are not included.

Identification of Semifixed Cartridge Cases and Charge

A cardboard or leatherbord cup is used to close the mouth of the cartridge case in a round where the cartridge case is packed separately. (See fig. 319.)

A label, found on the closing cup, contains information corresponding to the stenciling on the side of the fixed cartridge case. The information is as follows:

Details of the weapon.

Charge weight.

Kind.

Type (size and shape of the charge).

Place and date to manufacture of propellant.

Place and date of filling.

Indication of propellant charges for hot climates.

Cases with steel covers for packing and tranpsort, which are removed before loading, have neither labels nor stenciling relating to the propellant charge execpt the stenciling "Tp 25° C." imprinted on the base where applicable. Details of the propellant are availab-le, however, from the stenciling on the charge bags.

Stamping on the base of the case is the same as that on the base of a fixed round, execpt that the caliber of the equipment is sometimes omitted.

Markings on the Cartridge Bags of a "Semifixed" Round. These bags are marked similarly to the marking in fixed bags, execpt that the designation of the weapon is included. In some cases the caliber is not included. Bleidraht im Beutel indicates lead wire is included in the bag as a decoppering agent.

The number indicating the charge is marked prominently in black. The letter D often fol-lows this number and in some instances the marking is encircled by a red ring.

Sonderkart – Supercharge. With certain weapons additional charge sections, to be used for long ranges in place of those in the cartridge case, are supplied in cylindrical card-board packages. These section are numbered in continuation of those supplies for use at normal ranges in the case. Card-board packages containing these additional charge sec-tions are marked "Sonderkart" followed by the numeral of the section.

Marking of Primers for "Fixed" and "Semifixed" Ammunition

Designation – C followed by number.

Example: C/33

NA – New Pattern

St – Steel

Markings of Flash Reducing Charges

This charge is found in a flat circular silk bag and is identified by the words Kart.Vorl., followed by the abbreviation indicating the weapon with which used and the weight of the charge in grams.
