This is the NLAC Lublin 13, the Plage i Laśkiewicz (Lublin) R-XIII was an army cooperation plane which had a parasol wing and was powered by a Wright Whirlwind J-5, their main duties was observation and recon, but a few were later modified into light bombers. The Lublin 13 began production by New London Aeronautical Company as the
NLAC Lublin 13 Mk I (R-XIIIB) in 1932, then in 1933 the most numerous variant was produced, the
NLAC Lublin 13 Mk II (R-XIIID), which introduced a Townend ring on a radial engine, and a new engine cowling. The
NLAC Lublin 13 Mk III was a modification
which had small bomb racks installed under the wings, for a couple of 25 lb bombs under each wing, or a single 100 lb bomb under each wing. The Lublin 13s entered RIWAF service in 1932, and served in the Qaran Rebellion, Third Snow War, as well as the Saqan Mercenary War. By the time of the Third Snow War they were horribly obsolete, they were slow, with a maximum speed of just 116 mph, and the aircraft's rearward-firing 1x (or 2x) 0.303 Lewis (or Vickers K) machine gun(s) were off little defence against the more modern Snowlandian fighters, and even bombers.
