Just love the paintjob on your little beast. But I see you'we added some welds on the front of the turret, where the main body of the turret joins the gun-bearing part. When I built my (1/35) JS-2 I was told that that section was bolted from the inside so that the maingun could be removed.
That's the kinda thing people tell you when you'we completed the darn thing;)
But hey! Artistic license I say:D
