Hi,
all WWII VVS bombers profiles I have drawn recently I put into one picture in one commom scale. I took lengths (e.g. lengths of the planes alone without nose&tail guns) from different sourecs over web, TB-3 as the biggest one made as a refference (100%) and the lengths of the other planes are just calculated as a percentage from TB-3 length. So it is not any particular modellers scale, just relative dimensions. I have found it quite interesting, maybe you too. In some cases I was surpised how big or small this or that plane was.
