There is a non-zero chance I missed something important lol
Not a clue, perhaps some sort of smoke launcher?
Yes, it is a smoke launcher. The document was issued in November 1941 by the Kwantung Army Headquarters. The vehicle shown as an example is presumed to be the Type 92 armored car. For some reason, it is reversed left to right.
By the way, I think I accidentally deleted my previous comment. Since my original text is already included in your comment, I’ll just re-upload the photo.
A modified two-seat Mitsubishi A6M2 training and reconnaissance fighter from Rabaul, number 59-122. Only one plane of this type was built.
Double seat modified Zero 53-122 currently is even placed in Hirosawa museum
The A6M2 59-122 is interesting because, compared to the A6M2-K, it still has its full armament. The Mitsubishi A6M2-K had its 20mm cannons removed, but the A6M2 59-122 retained them during training and reconnaissance missions.
Is it actually 59-122? On JP wiki and museum plane is called 53-122
Oops, my mistake. Yes, it’s 53-122, not 59-122.
It is not Type 99 on new hull but just simple serial one
It can be clearly seen when comparing radiators placement and ledge on hull
This one vehicle:
Serial Type 99 on Type 89 base
New experimental hull

“Ka-Mi underwent testing with new engines, such as the one used in the amphibious tank Ka-Chi. It helped the Ka-Mi perform faster speeds in the water, going from 5.2 knots to 10.2, a drastic difference, but one that did not change the weakness the vehicle had of having thin armour as to allow amphibious use.”
Anything backing up this claim?
