FNAB-43
The FNAB-43 is an Italian designed and developed submachine gun manufactured from 1943 to 1945. The first prototype was built in 1942 and the ~1,000 built by the FNA-B according to Ian McCollum of Forgotten Weapons (''Fabbrica Nazionale d'Armi di Brescia'', "Brescia National Arms Factory", hence the name) were issued to German and Italian RSI ( Repubblica Sociale Italiana) units fighting in Northern Italy. The FNAB-43 was an expensive weapon to manufacture as it used extensive milling and precision engineering in its manufacture. Description The FNAB-43 uses a lever-delayed blowback system, firing from the closed bolt position. The bolt is a two-piece unit with a pivoted lever interposed between bolt head and body. Upon firing, the bolt head retracts, and begins to rotate the lever; the base of which is against a lug in the body. This lever is pivoted to delay the opening movement in order to allow the bullet to leave the barrel. The breech pressure then drops before the lever ha ...

Lever-delayed Blowback
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge. Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil , relative to the weight of the bullet, delay opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases. Other operating principles for self-loading firearms include delayed blowback, blow forward, gas operation, and recoil operation. ...

Italian Social Republic
The Italian Social Republic ( it, Repubblica Sociale Italiana, ; RSI), known as the National Republican State of Italy ( it, Stato Nazionale Repubblicano d'Italia, SNRI) prior to December 1943 but more popularly known as the Republic of Salò ( it, Repubblica di Salò ), was a German puppet state with limited diplomatic recognition which was created during the later part of World War II, that existed from the beginning of the German occupation of Italy in September 1943 until the surrender of German troops in Italy in May 1945. The German occupation regime provoked widespread national resistance, leading to the Italian Civil War. The Italian Social Republic was the second and final incarnation of the Italian Fascist state, oficially led by Benito Mussolini and his reformed anti-monarchist Republican Fascist Party. The newly-founded state declared Rome its capital but was ''de facto'' centred on Salò (hence its colloquial name), a small town on Lake Garda, near Brescia ...

World War II Infantry Weapons Of Italy
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submachine Guns Of Italy
A submachine gun (SMG) is a magazine-fed, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix " sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of SMGs were made for use by regular troops, clandestine commandos and partisans alike. After the war, new SMG designs appeared frequently.Military Small Arms Of The 20th Century. Ian Hogg & John Weeks. Krause Publications. 2000. p93 However, by the 1980s, SMG usage decreased.

Ian V
Ian or Iain is a name of Scottish Gaelic origin, derived from the Hebrew given name (Yohanan, ') and corresponding to the English name John. The spelling Ian is an Anglicization of the Scottish Gaelic forename ''Iain''. It is a popular name in Scotland, where it originated, as well as other English-speaking countries. The name has fallen out of the top 100 male baby names in the United Kingdom, having peaked in popularity as one of the top 10 names throughout the 1960s. In 1900, Ian was the 180th most popular male baby name in England and Wales. , the name has been in the top 100 in the United States every year since 1982, peaking at 65 in 2003. Other Gaelic forms of "John" include "Seonaidh" ("Johnny" from Lowland Scots), "Seon" (from English), "Seathan", and "Seán" and "Eoin" (from Irish). Its Welsh counterpart is Ioan, its Cornish equivalent is Yowan and Breton equivalent is Yann. Notable people named Ian As a first name (alphabetical by family name) *Ian Agol (born 19 ...

MAT-49
The MAT-49 is a submachine gun which was developed by French arms factory Manufacture Nationale d'Armes de Tulle (MAT) for use by the French Army and was first produced in 1949. Development In 1949, after evaluating several prototypes (including a collapsible design from Hotchkiss), the French MAT factory began production of the MAT-49 9 mm submachine gun. The MAT-49 used a machine stamping process which allowed the economical production of large numbers of submachine guns, then urgently required by the French Government for use by Army, French Foreign Legion as well as airborne and colonial forces to meet the need of a compact weapon. Production continued at Tulle until the mid-1960s, then switched to the Manufacture d'armes de Saint-Étienne plant (MAS), where the weapon was produced until 1973. In 1979, the French armed forces adopted the FAMAS 5.56 mm NATO assault rifle, and the MAT-49 was gradually phased out of service. Usage The MAT-49 saw widespread combat use ...

Northern Italy
Northern Italy ( it, Italia settentrionale, it, Nord Italia, label=none, it, Alta Italia, label=none or just it, Nord, label=none) is a geographical and cultural region in the northern part of Italy. It consists of eight administrative regions: Aosta Valley, Piedmont, Liguria, Lombardy, Emilia-Romagna, Veneto, Friuli-Venezia Giulia and Trentino-Alto Adige. As of 2014, its population was 27,801,460. Rhaeto-Romance and Gallo-Italic languages are spoken in the region, as opposed to the Italo-Dalmatian languages spoken in the rest of Italy. The Venetian language is sometimes considered to be part of the Italo-Dalmatian languages, but some major publications such as '' Ethnologue'' (to which UNESCO refers on its page about endangered languages) and '' Glottolog'' define it as Gallo-Italic. For statistic purposes, the Istituto Nazionale di Statistica (ISTAT) uses the terms Northwest Italy and Northeast Italy for two of Italy's five statistical regions in its reporting. These same su ...

Precision Engineering
Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time. These approaches have applications in machine tools, MEMS, NEMS, optoelectronics design, and many other fields. Overview Professors Hiromu Nakazawa and Pat McKeown provide the following list of goals for precision engineering: # Create a highly precise movement. # Reduce the dispersion of the product's or part's function. # Eliminate fitting and promote assembly, especially automatic assembly. # Reduce the initial cost. # Reduce the running cost. # Extend the life span. # Enable the design safety factor to be lowered. # Improve interchangeability of components so that corresponding parts made by other factories or firms can be used in their place. # Improve quality contro ...
