Hesham's entry on the N-62 Eaglet prompted a cursory Nihon University designation list. So, here's a rough designation list of the aircraft from the Mechanical Engineering
Department of Nihon University (Nihon Daigaku).
Designations (where available!) use a simple N-xx for powered aircraft and NM-xx for man-powered aircraft. The numbering series seems to follow the year of final design or introduction. If true, there is no real conflict between the reported N-75 Cygnus II light aircraft and NM-75 Stork man-powered aircraft.
There are lots of holes to be filled in ... Names are usually given in English but 'Shigunetto' pops up for the N-58 Cygnet. Does anyone know if this was widely used? If so, what's the romaji for the other names?
