By the way guys, i have been doing lots of research while building the Zeros (i always do so for any model i build). From movies to books to private collector of the real aircraft online. but what disturb me the most is that none of the pics i compare are the same to begin with interms of the detail and paneling. The are all Zeros but with different panel lines especially on the main wings. I know some of them are restore actual aircraft and some of them are replica from converted american AT-6 trainer that appear in movies Pear Harbour.. below are the reference pics
From private collector located in museum at Australia & USA 

Notice the panel lines are different on the wings compare to most kits we have. Also the body looks not smooth as though the metal are hammer to shape it 
 The under carriage views shows that this restore plane have the paint detailed correct. the grey is with a shade of blushis and greenish tint and the Dark Green are not on the yellow side as in some mistake restorer made on the Japan Army paint. Yellowish Green are more on the Chinese Army colour 
 Notice the marking of the Imperial round RED? some pics i have had a border of white on the top side but some don't. In Per Harbour the movies, all green ZEROs have marking without the white border. Any particular reason to it? i'm still searching for reference to that. 

This pics shows the pilot side of the panel. notice that there are only one visible lines? where as plastic models had lots of riverts on this section. No idea which one is correct. 
 Again the wing panel line are different from most plastic kit version 
 Image from the movie Pearl Harbour. notice again here that the panel details are not so complicated and different rfom model kits. 
 FRom the movies Pearl Harbour... notice the marking are without the white border...
Well you may ask why all the trouble? I don't have the intention to replicate the exact version of it in scale as that will kill the fun of modeling. This are all for my paint reference and no matter how we try, ours will still look like toy in the display shelf. But all these research had increase my gerenal knowledge of this machine that i don't process before building the kit. So research is also a way of widening your knowledge and not neccessarily on just being g=for the sole purpose of improving your build.
Cheers.
