HI
thanks for the Russian A-20 book link.
the camouflage is standard RAF, as some early Boston's were diverted from British contracts I think.
note the same camouflage lines on the nose. the 77 is some US delivery number, see below.
the other side.
The colours are Dark Green/Dark Earth uppers with Sky underneath. These were US made paints to British spcification but are
slightly different to British paint, the sky tending to be more cream and less green than the British specification I think. Nick Millamn wrote about this on his American Aircafrt for the RAF blog but that's invite only now.
Here one in the US before delivery, note the black 17 on the nose, same place and style as the 77 on the VVS plane above.
here are some from 88Sq in April 1942 [wiki sasy 1941 but it's wrong] as they are in the rpocess of having the rondles changed from A type [equal width rings] to C type [narrow yellow and white] note that Z2230, the plane in the fron has had the blue repainted, but not the red, as the codes got repainted to red as well, and the plane behind has red codes, this still has medium sea grey. There are load of colour photos from this date as well.
There is a photo in Red Stars 4 IIRC that has a wrecked plane and has a British serial visible.
But, also the liked book has some VVS Boston pics I've not seen before.
On page 79 of the linked book there is a VVS A-20G, which has the VVS nose conversion and this looks to be repainted with a pale colour.
I've not sen the pic on page 116 either, bort #70, ser no 39075
The wrecked A-20 on page 117 is interesting in clearly showing a painted out US star with bars, very unusual, and on page 118 there is a overall pale coloured A-20 with a caption about 'TSGAI' I think in cyrillic. This sounds familiar, but it's late and I'm too tired to look it up.[and if it's Red stars 4, book is a box ..not easily to get at ]
It maybe related to the pic of the post war A-20 which apperas at the bottom of page 119, which I think is also in Red Stars 4, which looks to have a VVS applied camouflage.
cheers
