Martinsyde F.4 Buzzard - Part two

The Martinsyde F.4 Buzzard was exported after the war to various countries as the RAF rejected it for service.
Ireland was one of those buyer countries as the Irish Government bought one (out of just four in the world) Martinsyde Type A Mk.II which was a transport variant of the Buzzard, to escape from the Anglo-Irish negotiations in case they failed. It was written off on 11th October 1927.
The Buzzard served also with the Irish Air Corps as at least four of them (this time in their fighter variant). They were bought from the Aircraft Disposal Company in  1922 which was the company that bought most of the Buzzards after Martinsyde went bankrupt. They served with the No.1 "The Humming Bird" Squadron based at the Baldonnel Aerodrome. Most of them were written off from 1925 until 1929.
It seems that the Imperial Japanese Army Air Service bought one airplane with testing purposes in the early 1920s from the Aircraft Disposal Company. Apparently they weren't impressed and didn't buy more of them. As we couldn't find graphical evidence of the Buzzard under Japanese command, the drawing should be considered as speculative.
The Karinės Oro Pajėgos (Lithuanian Air Force) bought two Buzzards in 1922 from the Aircraft Disposal Company where they served under the denomination of "Amerikietis" and "Amerikiete".
Under the command of the Wojska Lotnicze (Polish Air Force) it was bought in January 1921 and it served as a fighter until June 1923 when it was assigned to the Experimental section of the Military Aviation Research Centre. One year later, in winter 1924 it was repaired and repainted in white and red horizontal stripes to be the personal airplane of the Polish Air Force Commander who kept the airplane as his personal one until March 1926. 
The Buzzard was also gifted to Portugal in October 1919 and was assigned to the Arma de Aeronáutica Militar (Military Aeronautics Arm) where it served with the Grupo de Esquadrilhas de Aviaçao República (Republican Aviation Flight Group) formed in Amadora and later they were transferred to the Esquadrilha Mista de Depósito in the city of Tancos. A second batch of Buzzards arrived in 1923 and they were also assigned to the Esquadrilha Mista de Depósito which existed until 1926 when it disbanded and replaced by the Esquadrilha de Caça Nº1 (Fighter Squadron No.1) and served together with the Spad S.VII. They served until 1933.

Avro 504K European Users, part two

Now's the time for the second part of the European users of the Avro 504K.

• Ireland: The Irish Air Corps had six of them from 1922 until 1932. Further details are unknown.
• Latvia: The Latvian air force adquired two Avro 504K in 1924 and 1925 which were active until 1930 when they were replaced by the German Udet U.12 Flamingo.
• Norway: The Norwegian Army Air Service used some 504K apparently during the 1920 with a modified engine. Further details are, unknown.
• Poland: The Polish Air Force had one in inventory during the 1920s. 
• Russian Republic (Whites): Apparently one was used by the Slavonic-British Air Corps during the Northern Campaign of the Russian Civil War. Interestingly enough, it was used in the recon role, hence the observer machine-gun, instead in the training role.

Royal Aircraft Factory S.E.5 - Foreign Users

We keep drawing. This time it's the turn for the airplane that, arguably, was the best airplane of the whole Great War.

The Royal Aircraft Factory S.E.5 was a British biplane fighter of the first world war.
Given that we are covering the foreign users of this airplane, we are going to center on the S.E.5a model.
The S.E.5a model was an improved version of the initial S.E.5 model. It was powered by a 200hp Hispano-Suiza 8b engine and some of them were powered by a 200hp Wolseley Viper.

It was license built in the USA by the Austin Motor Company and also by Ebehart Aeroplane company.

The countries covered in this entry are:

• Argentina: The Argentine Naval Aviation bought some of them as late as 1927 and used them as advanced trainers.
• Australia: Some SE5a were given to Australia as part of the imperial gift after the end of the Great War and they constituted the backbone of the very early Royal Australian Air Force (RAAF). They served until 1929 when they were replaced by the Bristol Bulldog.
• Canada: The Canadian Air Force employed SE.5a together with Sopwith Dolphin in the No.1 fighter squadron. However, as we couldn't fin graphical info, both the colours and registrations are speculative.
• Chile: The Chilean Military Aviation Service bought some SE.5a in 1924 to equip the newly formed 1st Aviation Company.
• Ireland: Apparently one SE.5a served in the Irish Air Corps during the Irish Civil War. It operated from the Fermoy aerodrome, in southern Ireland and was destroyed due to an engine failure. We couldn't find graphical evidence, so the drawing must be considered as speculative.
• Japan: The British Aviation Mission on Japan took one Viper-engined SE.5a to Japan after the armistice in order to serve in the Imperial Japanese Navy Air Service. We couldn't find any graphical info about that airplane so it must be considered as speculative.
• Poland: The Polish Air Force bought at least one ex-RFC from the United Kingdom and was used in the Polish-Soviet war.
