I forgot to add: If you look at the first picture that I posted, of white 61, I figured that is probably more or less what white 14 would have looked like while operational. If my guess is correct, it is quite clear from the walkaround of white 14 that the individual colours faded differently and at different rates... I was aiming to more or less match the colours that I see in the picture of white 61.
I think it's a somewhat similar scheme -- The light brown (sand), light green and olive drab all seem to match my interpretation of the scheme on Bort 14; but I don't think the very dark olive green (which I'm guessing is replicated by AKAN 63024) was used on it, being replaced instead by patches of the dark chocolate brown. BTW, I'm pretty confident that the AKAN Sand and Dark Brown colors are good matches. As I said above, you might want to check out AKAN 63055 as a possible candidate for the light green color.
Yes, I'm aiming for fresher, less faded colors. The model is presently gloss-coated while I apply the numerous stencils. (Whether or not they should be present is probably controversial, but some of the walkaround photos do show traces of blue and red stencils, so I'm proceeding). I'll post a couple of photos once she's flat-coated and gives a better impression of the paint job.
