Replica is built by Latvian enthusiasts from original, century-old plans. Tthey had spent 15 years scouring archives in Latvia and neighboring Russia for plans of the plane, which was designed by French aviator and aircraft designer Henri Farman.

They then spent three years building the 560-kilo (1,234-pound) plane, which has an original 1912 US-made Curtis motor.
With a maximum speed of 74 kilometres per hour (46 miles per hour), the Farman 4 was the fastest plane of its era. Originally produced in France, it rapidly gained hold elsewhere, including Tsarist Russia, which ruled Latvia at the time.
