my New Year's resolution is that perfect is the enemy of good.
So I will not translate original orders or other original material, but I will nether less offer my consideration on the I-15bis page.
The first consideration is that the profiles are really very nice: I do not know if Mr. Tuomanen is a professional illustrator, but in my eyes he lacks nothing to be one!
About the colors of No. 62, I have read the topic in scalemodels.ru that Massimo reported in the thread: Re: polichromatic camouflages and unknown AMT of December 30, 2016.
If I have not misunderstood it, and oversimplifying, it states three points:
1) In 1941 some new planes, from some specific factories, were finished in three color uppersurface camouflage.
2) Many new planes were finished in black/green uppersurface camouflage.
3) Many old planes were finished with various amounts of green and black on their uppersurfaces.
So I suggest that No. 62 could just be a “normal” grey/silver plane, with uppersurfaces painted with large bands of green and thin bands of black.
Of course we all know that it is impossible to reconstruct with certainty colors from gray scale photos, but as in this forum it is possible to discuss various possibilities in a polite and civilized way, I tried a very crude experiment: I copied the photo of 68 from Massimo’s site, then I copied a small rectangle from the undercarriage (No. 1), and pasted it in different places of the fuselage on the dark color (No. 2) and on the light color (No. 3) which I supposed had lighting similar to the undercarriage.
No science at all, but you can see that it is almost impossible to distinguish the rectangle from the rest of the light camouflage.
Of course I could be proved wrong, but I swear that I would like to see a profile with these colors, especially if done by Mr. Tuomanen!
