Morane-Saulnier Ms.230, foreign users, part two

 

The Morane-Saulnier Ms.230 was a French two-seat single-engine trainer aircraft from the late 1920s that served, in many variants, with various countries all around the globe until World War 2. We already covered some of them in our previous post, so here are the remaining ones:

• Greece: Eighteen Ms.230 were ordered by the Royal Hellenic Air Force (RHAF) in October 1930 and were delivered in 1931. They were the main elementary trainer of the RHAF until 1936 when they were replaced by the Avro Tutor. The Ms.230s were not, however, written off, as they were kept as advanced trainers until the beginning of World War 2.
• Portugal: This Iberian country had its own version of the Ms.230; the Morane-Saulnier Ms.233 was powered by a Gnome-Rhône 5Ba or, in the latest versions, the Gnome-Rhône 5Bc which delivered, both of them, 230 hp of power. Six of them were built in France and 16 in Portugal by OGMA (Oficinas Gerais de Material Aeronáutico - General Workshops of Aeronautical Material). The were the main trainer of the Portuguese Aeronautical Corps during the 1930s and some of them were exported to Spain.
• Romania: In 1931 the Royal Romanian Air Force (RRAF) bought twenty Ms.230. They were used as their main trainer. As we couldn't find any graphical evidence of the Ms.230 serving in Romanian colours, the drawing should be considered as speculative.
• Switzerland: In 1931 the Swiss Flugwaffe (Swiss Air Force) bought two Ms.229 for basic training. These machines were identical to the Ms.230 but were powered by an Hispano-Suiza 8a V8 engine. This engine turned to be problematic as the engine failed in mid air various times, luckily, without any loss. After some investigations on the causes, it was found that the engine wasn't suitable for acrobatics, so one of them, numbered 643, was re-engined in 1932 with an American Wright 9Qa radial engine, licensed made in Switzerland as Hispano-Suiza 9Qa. Flight performance was improved, but only one machine was brought to that standard. They were kept in active until 1939 when they were withdrawn from active service.
• Slovak Republic: During late 1940 or early 1941, a single captured Ms.230 was given to the newly established Slovak Flying Corps. This single Ms.230 was kept at Vajnory airfield, as glider tug. It was probably destroyed in March 1945. Apparently there was a second machine which was given without its engine and was used for spare parts.
• Republican Spain: The Fuerza Aérea Republicana Española (FARE - Spanish Republican Air Force) bought six Ms.233 from Portugal at the beginning of the Spanish Civil War. They were employed as elementary trainers at La Rivera flying school. 
• Venezuela: In 1930 Venezuela acquired three Ms.230 for their Regimiento Militar de Aviación Nº1 (No.1 Military Aviation Regiment - de facto the Venezuelan Air Force during the 1930s and part of the 1940s). They were kept in active until late 1930s when they were replaced by more modern types.

Avro 504O

The Avro 504O was a floatplane version of the 504N which was made in 1925 at Manchester.
It was powered by the same Armstrong Siddeley Lynx IVc which could deliver up to 180hp of power.

• Brazil: The Brazilian Navy bought some 504O to equip some floatplane squadron. Anyway further information is unknown so the drawing should be considered as speculative
• Chile: The Chilean Navy also had some 504O in service, most probably to replace the previous outdated 504L floatplanes. Unfortunately any graphical info seems impossible to find and the drawing should be taken as speculative.
• Greece: The Greek Navy bought some of them in 1925 together with some 504N and they even produced some of their own in the Kratiko Ergostasion Aeroplanon (State Aircraft Factory) in 1935 before switching to the more advanced Avro 621 Tutor. The 504O served, just like the 504N until 1936.
• Japan: The Imperial Japan bought some 504O most probably to replace the outdated 504L. However as we couldn't find precise information, the drawing should be taken as speculative.

Avro 504N - European Users

Th Avro 504N was an improved version of the Avro 504K, with a new engine and some other aerodynamical changes which consisted on a new undercarriage, new wings, a new engine and the removal of the skid. Some internal improvements were also made like the inclusion a direct gravity feed for gas.

It was used by many European countries as it became their standard trainer airplane and it was license built in Belgium by SABCA during the late 1920s until mid-1930s, and in Greece by the Kratiko Ergostasio Aeroplanon (State Aircraft Factory) from 1934 until 1935.

It was powered by either a 150hp or 180hp Armstrong Siddeley Lynx IV engine.

• Belgium: It was the backbone of their trainer squadrons during the 1930s decade. Some of them were still in service when Germany invaded Belgium in May 1940.
• Denmark: The 504N was also the main trainer of the Royal Danish Air Corps during the late 1920s until the mid 1930s. It's worth to mention that these airplanes were equipped with a cowling in the back seat in order for the student to learn how to "blind pilotage".
• Greece: The Greeks ordered some 504N in 1925. 
• Sweden: In December 1925 the Swedish Army Aviation Company ordered five 504N which were delivered in April 1926. They served under the denomination of Sk-3 and Sk-3A in the Flying School at Ljungbyhed. Surprinsingly, they served only until 1928 as they couldn't cope wheel with the harsh cold Swedish weather.
• United Kingdom: The 504N replaced the 504K as the main RAF trainer during the 1920s.

Avia BH-33E

The Avia BH-33E appeared first on 1929 and it differed on the original BH-33 and the PWS-A in various aspects.
The slab-sided wooden fuselage was replaced by a welded steel-tube structure, it had an elliptical cross section achieved with the help of light formers and a spli axle vee-type undercarriage introduced to replace the original crossed-axle undercarriage.

Even if it wasn't originally ordered by the Czechoslovak authorities, which waited until the BH-33L, it did have some export success and three airplanes were bought by the USSR to preform some tests and 20 were sold to Yugoslavia which also purchased a production license, for the firm Ikarus at their plant of Zemun, close to Belgrade.

Two sub-variants were made one powered by the Bristol Jupiter VI, and the other one, which was the most produced, powered by the supercharged version of the Bristol Jupiter VII. One single BH-33 was fitted with a German BMW Hornet engine, however, as we couldn't find any graphical evidence, we haven't drawn it. It was armed with two Vickers 0.303in machine guns placed in the frontern upper part of the fuselage.
