Well, the internet is a great place to find reference -especially on Russian stuff. So between walkarounds and online books I finally foudn out how was done most of the interior for that T-26 tank, plenty of plasticard. I still have to do all the cases and stuff on each side of the direction bar.
So here is another view of the inside with the opening for the rear wheel.
here is the front and top of the T-26, lots of Scale Hardware rivets added as well as a few PE details (that were left from the King Child diorama)
Some modeler cliché perhaps? okay, "PE hell", accurate for those Aber fenders, the are really hard to solder
