[4] In addition, six Maake IIs were completed at by Norsk Aeroplanefabrikk (Army Aircraft Factory) when the company initially contracted to build them failed to deliver, although these were later handed over to the Navy, along with four additional newly manufactured Maake IIIs built at Haerens Flyvenmaskinfabrikk/Kjeller Flyfabrikk, as the Army no longer had any need for them.
[4] In 1921, Finland obtained the manufacturing license for the W.33 and the first Finnish-built example flew on 4 November 1922, as the IVL A.22 Hansa.
These were not popular in Japanese service due to inadequate directional control and poor downward visibility from the cockpit, but were flown from the battleship Nagato for seaplane trials in 1926.
[8] Latvia received two IVL A.22s from the Finnish Air Force in December 1926, however both were completely wrecked the following March, prompting a major rebuild, which some sources have counted as two additional aircraft having been built.
