Thanks evangilder for your favorable words for me but -
Now, Wayne - a very expert of Zero fighter seems coming up, I have re-checked my
knowledge about the A6M1 to update.
Correction with apology
Type 12 Experimental Carrier Fighter was a prototype for Type 0 Carrier Fighter (Zero fighter).
It had two models - A6M1 and A6M2a.
A6M2a was later designated as Model 11.
A6M1 had only two planes.
The illustration of engine cowl already belongs to old knowledge.
The latest understanding is there was no extruded air-intake on the engine cowl.
Also, the body and wing color was not orange but green-gray.
As a result, it has been turned out that the appearences of A6M1 of
the link I introduced is correct.
Thanks.
