Hi paul , the soviet schemes have always usually been quite simple , national markings and a bort number . Occasionally you can get a slogan on the side or more often different coloured areas (striped rudder , coloured cowling etc.) but the actual aircraft markings are always the same . The onme thing that differed about these is the colour of the bort number and the style of the red star -as a general guide , the earlier stars had a 3d effect with one half of each arm in a darker shade of red, a bit later and they were all one shade without borders and later still with a white or sometimes yellow border. So even though it seems they all look the same its right ,unless its Kozhedubs La 7 bort no 27 , thats a whole different can of worms!! heres a link to a good site http://vvs.hobbyvista.com/ hope this helps , cheers tony
