KN-1F TexanM
Designed in the late 1930s, the North American NA16 design, commonly known as the AT-6 Texan, has been declined in a great number of versions and sub-versions, most of them able to carry weapons, some of them being carrier capable.

Among the many thousands airframes produced, one has a
has a peculiar story.  In South Korean service, an AT-6F (or a SNJ6 for that matter, s/n 44-81691) was recovered after a crash and converted into a seaplane.   This conversion involved the construction of the floats themselves, and the removal of surperfluous equipment.  Depending the source, the main float was either a one-off construction or the adaptation of the main float of a WWII Japanese seaplane, the Rufe.
   
For the purpose of AAC, this particular version of the Texan will differ very little from the two other variants of the same aircraft and those differences will essentially be the consequence of a different empty weight, hence a slightly different weapons carrying capacity (since the overall weight limit remains unchanged).  Based on various readings :
