QF 13-pounder 6 Cwt AA Gun
The Ordnance QF 13 pounder Mk III anti-aircraft gun, also known as 13 pounder 6 cwt, was an early British improvisation in World War I to adapt the QF 13-pounder field gun to anti-aircraft use. 6 cwt referred to the weight of barrel and breech (6 × 112 lb = 672 lb) to differentiate it from other "13 pounder" guns. History This was a standard QF 13 pounder field gun barrel and breech with the addition of a retaining catch to the breech to retain the round when loading at high angles. It was first approved in October 1914 and was issued on Mk I high angle mounting, usually mounted on a motor lorry. The Mk I mounting had an additional recuperator housing mounted directly above the normal recuperator to facilitate gun runout at high angles. Hence the appearance was of a gun barrel with 2 slightly shorter tubes of similar diameter above it. Mk II mount improved the usability, added deflection gear and the recoil system was improved so that the additional recup ...

QF 3 Inch 20 Cwt
The QF 3-inch 20 cwt anti-aircraft gun became the standard anti-aircraft gun used in the home defence of the United Kingdom against German Zeppelins airships and bombers and on the Western Front in World War I. It was also common on British warships in World War I and submarines in World War II. 20 cwt referred to the weight of the barrel and breech, to differentiate it from other 3-inch guns (1cwt = 1 hundredweight = , hence the barrel and breech together weighed ).

Design and development The gun was based on a prewar Vickers naval QF gun with modifications specified by the War Office in 1914. These (Mk I) included the introduction of a vertical sliding breech-block to allow semi-automatic operation. When the gun recoiled and ran forward after firing, the motion also opened the ...

World War I Artillery Of The United Kingdom
The world is the totality of entities, the whole of reality, or everything that exists. 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 parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality 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 contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Ian Allan Publishing
Ian Allan Publishing was an English publisher, established in 1942, which specialised in transport books. It was founded by Ian Allan. In 1942, Ian Allan, then working in the public relations department for the Southern Railway at Waterloo station, decided he could deal with many of the requests he received about rolling stock by collecting the information into a book. The result was his first book, ''ABC of Southern Locomotives''. This proved to be a success, contributing to the emergence of trainspotting as a popular hobby in the UK, and leading to the formation of the company.Ian Allan…the man who launched a million locospotters '' The Railway Magazine'' issue 1174 February 1999 pages 20-27 The company grew from a small producer of books for train enthusiasts and spotters to a large transport publisher.

On 18 February 1915 Sir John French, commander of the British Expeditionary Force (World War I), British Expeditionary Force in France, asked for an anti-aircraft gun with a muzzle velocity of . On 19 August 1915 the Army Council proposed adapting existing 18-pounder guns (3.3-inch bore) to use 13-pounder (3-inch) shells, thus meeting the requirement for higher velocity. ...

Macedonian Front (World War I)
The Macedonian front, also known as the Salonica front (after Thessaloniki), was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the autumn of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and with insufficient force to prevent the fall of Serbia and was complicated by the internal political crisis in Greece (the National Schism). Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian front remained stable, despite local actions, until the Allied offensive in September 1918 resulted in Bulgaria capitulating and the liberation of Serbia.
