Context_1 : The Britney Spears doll is a celebrity doll made in the likeness of pop singer Britney Spears. Several versions of the doll were released. Each doll is dressed in costumes that resemble the clothing Spears had worn in concerts, appearances, and music videos. The Britney Spears doll was the first doll produced by Play Along Toys. Context_2 : MCEM-2 (Machine Carbine Experimental Model 2) submachine gun was produced only in prototype form, but was one of the very first submachine guns to combine wrap-around bolt and magazine in pistol grip, features later copied in the Czechoslovak Sa vz. 23, Israeli Uzi and a great number of other submachine guns. MCEM-2 was the second prototype in a line of experimental submachine guns, designed in Britain in 1944. It was envisioned as a possible replacement for the STEN submachine gun then in service. The MCEM-2 was developed by Jerzy Podsedkowski, a Polish constructor involved in work on Vis and Mors, who fled from occupied Poland to Britain. It is believed that prototypes of MCEM-2 were made before the end of WW2, and its derivatives MCEM-4 and MCEM-6 were tested soon after the war. The latter modifications differed mostly in adoption of the rate-reducing mechanism, incorporated into trigger unit; the rate of fire therefore was decreased from 1000 to more realistic 600 rounds per minute. Nevertheless, neither prototype was found suitable for adoption, and several years later British army adopted a more conventional submachine gun, the Sterling-Patchett. Context_3 : The Sterling submachine gun is a British submachine gun. It was tested with the British Army in 1944–1945 as a replacement for the Sten but it did not start to replace it until 1953. It remained in use until 1994, when it was phased out as the L85A1 assault rifle was phased in. Context_4 : Jenny (ジェニー , Jenī ) is a 10½ inch fashion doll produced by Japanese toy company now known as Takara Tomy since 1982. The doll was known as "Takara Barbie", and in 1986 the doll was renamed "Jenny" after Takara ended their licensing agreement with Mattel.Takara Barbie differs from a western Barbie. Takara Barbie was altered to better appeal to Japanese preferences, with a shorter height, large rounded manga-style eyes and a closed mouth. The doll's physical figure is more natural than the Western Barbie's exaggerated figure. Like her Western counterpart, Jenny wears a large variety of outfits, which often include street fashion, school uniforms, kimonos, and other uniquely Japanese costumes, such as "Bullet-Train Stewardess Jenny". Today the Jenny doll is a sentimental favorite doll in Japan, but she is much less popular than Licca-chan, Japan's market leader fashion doll. Context_5 : Sindy is a British fashion doll created by Pedigree Dolls & Toys in 1963. A rival to Barbie, Sindy's wholesome look and range of fashions and accessories made it the best-selling toy in the United Kingdom in 1968 and 1970. After Marx Toys' unsuccessful attempt to introduce Sindy in the United States in the late 1970s, Hasbro bought the rights to Sindy and remodelled the doll to look more American. As a result, the doll's popularity declined and Barbie manufacturer Mattel filed a lawsuit for copyright infringement, which was settled when Hasbro agreed to remodel Sindy's face. During the 1990s, Barbie's share of the doll market continued to grow while Sindy's diminished, which led to Sindy being delisted from major retailers in 1997. Hasbro returned the doll's licence to Pedigree, and the doll was relaunched in 1999, manufactured by Vivid Imaginations. Sindy's 40th anniversary in 2003 saw a new manufacturer, New Moons, and another relaunch and redesign. Context_6 : Pedigree Dolls & Toys, also known as Pedigree Toys, is a toy company located in Exeter, England. Best known for launching the Sindy doll in 1963, Pedigree also produced the Tommy Gunn action figure from 1966 to 1968. The Sindy doll was very popular from the 1960s to 1980s, and accounted for 80% of Pedigree's sales. Context_7 : The Type 100 submachine gun (一〇〇式機関短銃 , Hyaku-shiki kikan-tanjū ) was a Japanese submachine gun used during World War II, and the only submachine gun produced by Japan in any quantity. It was made in two basic variants referred to by American and British observers as the Type 100/40 and the Type 100/44, the latter also known as the Type 100 (Simplified). A third variant was a folding version of the early model, sometimes referred to as the Type 100 Navy, made for parachutists. Context_8 : Tommy Gunn was an Action figure or boys' doll produced by Pedigree Toys Ltd from 1966 until 1968. The basic doll depicted a British infantry soldier of the time complete with Sterling submachine gun but was also available in World War II dress carrying a Sten gun. The figure was in direct competition with Action Man by Palitoy and in the same manner as the competing product, offered a variety of alternative outfits and accessories. Context_9 : The Arsenal M23 submachine gun (Estonian: "Arsenali püstolkuulipilduja" ) (also known as Arsenal Tallinn) was an Estonian submachine gun from 1926 through 1935. These submachine guns were designed and produced in the Estonian military equipment factory "Arsenal" in Karjamaa, Tallinn, but production was not more than 600 units. The weapon was chambered for the 9x20 mm semi-rimmed Browning cartridge to be compatible with ammunition for the Browning FN M1903 pistol which had been adopted by the Estonian Army. It operated on the blowback system and was essentially similar to the MP18.1; having a wooden stock, slotted barrel jacket, and horizontal left side magazine feed. A uniquely slender 40 round single column box magazine led to frequent cartridge feeding problems; and cooling fins which were machined lengthwise along the barrel to promote cooling air flow when firing (similar to the Lewis machine gun), unnecessarily complicated production. It was used by the combat support units of the Border Guard, the Estonian Defence League and the Estonian Defence Forces. The Arsenal submachine gun was replaced in Estonian service by the Finnish Suomi KP/-31 submachine gun in 1938. The Estonian Army sold a few samples to Latvia and all of the remainder found their way to Republican forces during the Civil War in Spain. Context_10 : The Hyde-Inland M2 was a United States submachine gun design submitted for trials at Aberdeen Proving Ground in February, 1941. Work was undertaken by General Motors Inland Manufacturing Division to develop workable prototypes of George Hyde's design patented in 1935. The model first submitted for trials in April 1942 was designated the "Hyde-Inland 1". Trials revealed the design was superior to the M1 submachine gun in mud and dirt tests, and its accuracy in full-automatic firing was better than any other submachine gun tested at the time. An improved "Hyde-Inland 2" was designated U.S. Submachine gun, Caliber .45, M2 as a substitute standard for the M1 Thompson in April, 1942. As Inland's manufacturing capacity became focused on M1 carbine production, the US Army contracted M2 production to Marlin Firearms in July, 1942. Marlin began production in May 1943. Marlin's production failed to match the trials prototype performance; and Marlin's original contract for 164,450 M2s was canceled in 1943 upon adoption of the M3 submachine gun. The M2 is chambered for the .45 ACP cartridge and used the same 20- or 30-round magazine as the Thompson. Its cyclic rate of fire is 570 rounds per minute. None of the approximately 400 manufactured were issued by any branches of the United States military. fact_1 :  The basic doll depicted a British infantry soldier of the time complete with Sterling submachine gun but was also available in World War II dress carrying a Sten gun. fact_2 : The Sterling submachine gun is a British submachine gun.
