Without knowing it from the outset, the Avro Type 504 series of aircraft would become one of the most produced and influential biplane designs for the United Kingdom, being fielded from 1913 all the way through the early 1930s. The design originally started as an armed reconnaissance biplane but quickly was relegated to the training role with the advent of new and better performing fighter aircraft. This new role would help the Avro 504 to shine in Royal forces service for decades to come.
The Avro Type 504, at its core, was a single engine biplane design. Depending on the model series, crew accommodations amounted to one or two personnel. Armament was usually a forward flexible-mounted Lewis machine gun of 7.62mm caliber. Additional stores in the way of bombs could be affixed to underwing portions of the aircraft. Early models also contained a landing skid in addition to the fixed landing gears, though this skid would be removed in subsequent models.
The legacy of the Type 504 would begin as a further design of the Avro Type 500 basic trainer. With an order placed by the Royal Navy and Royal Army of Britain, the Type 504 was in service by 1913 with its Gnome Rotary engine generating a perceived 80hp which amounted to more like 60hp in practice. Early combat experience saw the Type 504 conduct limited strikes against ground targets with the more-than-occasional Zeppelin-busting sortie to boot. Though a success in these roles, the advancing technology of wartime research forces the Type 504 into training duties by 1914.

The Type 504 proved to be a versatile performer as proven by the myriad of variants produced featuring minor structural revisions, new designations for specialized roles and a plethora of engine fittings. The Type 504K model represented the two-seat version whilst the 504C amounted to a specialized anti-Zeppelin mount. Float pontoons would go on to produce the Type 504L floatplane while the Type 504M was relegated to transport duties. By the end of the war, the system was still seeing production and would see nearly 600 more added to the 10,000 plus total between the years of 1925 and 1932. These would be designated as the Type 504N models and be new production or converted models of existing Type 504s. Type 504s would eventually be superceded by the Avro Tutor aircraft series.
In the end, the remarkable Type 504 series would become one of the most endearing aircraft of its generation. Many a military pilot would owing his wings to having trained on the platform and many more civilian pilots would as well. The Type 504 would become a mainstay of the famous "barnstorming" touring groups as well as becoming a prized collector piece to the avid flyer.
