I need some of Your help to complete my list of the Army aircraft.
The green highlightings in the list indicate that there are doubts concerning configuration or role
of an airplane.
If there really were double numbering of Ki-2, Ki-4 and Ki-7 ?
If in any case the producer in the list is placed properly ?
I've got many doubts and questions and I'll be very grateful for any answer
and indication of inaccuracy

According to Rene Francillon's Japanese Aircaft of the Pacific War:
Ki-2: Mitsubishi Army Type 93, Twin Engined Light Bomber, Japanese version of Junkers K-37
Ki-4: Nakajima Army Type 94, econnaissance plane
Ki-7: Mitsubishi Army experimental crew trainer

The book contains a full list of the Ki designations as well as other (complex) Japanese military aircaft designations.

No suggestions from my part. I am not an expert in Japanese aircraft but jst have the book on my shelves.
I suggest you try this in a Japanese specialist forum at http://www.j-aircraft.org/smf/index.php.

source:Japanese Aircraft 1910-1941--Robert C.Mikesh & Shorzoe Abe
Putnam.Conway Maritime.London 1990.page 184.
(according to the text,based on the Junkers K.37)

It's OK, good people, but I've got Mitsubishi Ki-2, Nakajima Ki-4 and Mitsubishi Ki-7 in my list
since a long time.
Now I'm looking for a confirmation that my " Encyklopedia Lotnictwa Wojskowego " is right
and Kawasaki Ki-2, Ki-4 and Ki-7 really existed.
Have anybody seen the list at all, 'cause still You talk only about those three airplanes ?

The Type 88, Type 91 and Type 92 designations indicate that these aircraft were accepted for service in 1928, 1931 and 1932 respectively, which tallies with all my references.

The Kitai system was not adopted until 1933, and was intended for new aircraft development specifications from this time. I have not seen these Kawasaki Kitai dsignations anywhere else, and I suspect they are not original asignments.
