170th Bakugekitai.
This squadron was hastily put together near wars end with surviving aircraft from several squadrons.
These are the colour photos that I had mentioned before in this thread with the two different painted fuselages assembled together. I don't know much about film,some are without a blue filter and there is a few with the blue filter that gives a natural colour appearance.
In the photos there is three different colours shown a solid light grey with a glossy finish all the way at the rear with partial view of the tail number.
I believe its is #227.
A couple of solid green aircraft.
#104 & #458.
Then we get into the third colour blue/grey #516 has its rear portion painted in this manner.
The Japanese used this colour on a number of their aircraft and a few colour photos and actual aircraft parts painted this way exist today.
Greebo has dibs on #516 everyone.
Then in the last photo we have a green and grey combination on #079.
Difference in appearance with the filter.
Close up view black and white of the demarcation line.
The problem with black and white photos there could be many of these aircraft painted in the blue/grey scheme.
No way of telling sadly.
