Original Item: Only One Available. This is an excellent example of a German WWII Kriegsmarine Female Auxiliary (Marinehelferinnen). The overseas cap, nicknamed in German military slang as Schiffchen, or literally "little ship" as it resembled an up-turned row-boat, was standard issue for Warrant and Petty officer NCO ranks.

The cap is constructed of a navy blue wool exterior, and features BeVo machine embroidered Wehrmachtadler Eagle on the front of the flap, made from golden yellow thread on a blue background. This version of the cap does not have the tri-color cockade sometimes seen. The scalloped flap around the cap has lovely golden yellow wool piping around the top, indicating officer issue. The interior is black cotton, and is in very good condition. The inside has complete maker, size, and date information:

1944
RB Nr. 0/0415/0023
58

Condition of the cap is very good, showing little to no wear from service on the exterior, and the interior doesn't have any staining we can see from use. There is a bit of fraying of the bottom end of the piping behind the clap. The colors are still vibrant, and there are two gold yellow stitches above the eagle to keep the front of the cap from folding down.

A fantastic well marked Kriegsmarine Female Auxiliary (Marinehelferinnen), ready to add to your collection!

Beginning in 1940, the Wehrmacht established its first female auxiliary organization with the creation of the Heeresnachrichtenhelferinnen (Army Signals Communications Auxiliaries). Similar auxiliary services were subsequently introduced within the Army and extended to the other branches of the German armed forces. Initially, recruitment was conducted on a voluntary basis; however, by December 1941, unmarried women between the ages of 18 and 40 became subject to compulsory service in these auxiliary roles.

All female auxiliaries were issued uniforms and were subject to military discipline, receiving rations, accommodation, and clothing provided by the military. Despite this, they were not considered members of the armed forces proper but were classified as auxiliaries attached to the Wehrmacht. Accordingly, they were compensated under civilian civil-service pay scales, and their rank designations did not correspond to standard military ranks.

The Kriegsmarine was the navy of NSDAP Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war Reichsmarine (1919–1935) of the Weimar Republic. The Kriegsmarine was one of three official branches, along with the Heer and the Luftwaffe, of the Wehrmacht, the German armed forces from 1935 to 1945.

In violation of the Treaty of Versailles, the Kriegsmarine grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines.

Kriegsmarine ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans.

In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favor of a crash building program for submarines (U-boats) instead of capital surface warships, and land and air forces were given priority of strategic resources.

The Commander-in-Chief of the Kriegsmarine (as for all branches of armed forces during the period of absolute NSDAP power) was Adolf H, who exercised his authority through the Oberkommando der Marine ("High Command of the Navy").

The Kriegsmarine's most significant ships were the U-boats, most of which were constructed after Plan Z was abandoned at the beginning of World War II. Wolfpacks were rapidly assembled groups of submarines which attacked British convoys during the first half of the Battle of the Atlantic but this tactic was largely abandoned by May 1943 when U-boat losses mounted. Along with the U-boats, surface commerce raiders (including auxiliary cruisers) were used to disrupt Allied shipping in the early years of the war, the most famous of these being the heavy cruisers Admiral Graf Spee and Admiral Scheer and the battleship Bismarck. However, the adoption of convoy escorts, especially in the Atlantic, greatly reduced the effectiveness of surface commerce raiders against convoys.

Following the end of World War II in 1945, the Kriegsmarine's remaining ships were divided up among the Allied powers and were used for various purposes including minesweeping. Some were loaded with superfluous chemical weapons and scuttled.

Reichsbetriebsnummer or RB number (also represented as RB Nr or Rbnr). Before the war, the Germans set up a system for registering and recording the factory information, the Reichsbetriebskartei. This was to help enable machine tabulation of facts and figures. It was from this that the Reichsbetriebsnummer came into being. The Reichsministerium für Rüstung und Kriegsproduktion (Ministry for Armaments and War Production) files survive today in the Bundesarchiv, however, these are only fragmentary. There is a holding file from the working group created by the Office of Machine Reporting in the Armament Office of the Reich Ministry for Armaments and War Production - their main focus was the operations of the industry group for which an economic interest was Armour production. This index provides information on the most important data of the companies covered by it, production profile, operating area, number of employees and the responsible operator.

As a prerequisite for the intended use of the punch-card method in the armaments industry, it was this system which gave rise to the Rbnr. The operating numbers were assigned by the competent local district offices of Machine reporting. (Bezirksstellen des Maschinellen Berichtswesens.) The index is in the form of index cards that are accessible numerically (approximately 14 meters of index cards!). Access to this register is only possible through the naming of this company, stating the place of production. The Reichsministerium für Rüstung und Kriegsproduktion files have multiple entries on the introduction of the factory and also the lot no.

The Rbnr code was used from 1943 onwards and replaced the makers name and address (or company logo) on government contract uniforms, caps and field equipment and knives. It is either rubber ink stamped on cloth or die stamped onto leather & metal items. It has been written countless times that this numeric code system was introduced as a security measure to help mask production locations. This was not the case but it was perhaps, a helpful by- product of the system. It is not unknown to find the Rbnr together with the maker’s info. Had it been a security measure, clearly this practise would have been banned.

So what was the Rbnr? It was a nine digit number and was normally represented thus: RB Nr: 0/000/0000.
