An interesting tidbit about the Rufe is that it was actually designed and built by Nakajima, Mitsubishi didn't have anything to do with it (other than designing the original airframe of course).
Trainer version next..A6M2-K, followed by the next variant, the A6M3 Model 22 and 32....the Clipped wing model 32 actually entered service first.
The main visual difference is a more streamlined cowling to accomodate a larger engine.
Agree, and it seems that Japanese aircraft offer plenty of scope for weathering/paint wear - great! Seeing all these has reinforced my idea of doing a 'Luftwaffe' Zero, but, from what Catch said, would it be Nakabishi, or a Mitsujama?! That trainer, with two seats, has the look of a Dauntless, don't you think? Great pics BTW Wayne.
