Slowly getting somwhere with my IS-3
I had to make a little bulkhead so the upper hull would not bow down in the middle.

Basic construction of toolboxes done, each has 3 little bulkheads inside, they are quite sturdy.

Et voilà, upper hull glued. I've added 0,3 mm styrene shims to the sides of the glacis armor for better fit and to blank the empty space just behind the idler.

Here are the additional ventilation louver slots on the rear engine deck. Tamiya made 6 per side, while there should be 7 as on original tanks. They may have come out a bit wider than should be, I will see how that looks like after primer and maybe then try to improve their appearance.

And a test fit of the turret.

Cheers,
Greg
