The StuG III G was one of the longest running production vehicles (and one of the largest # produced) in the German inventory with a lot of changes/tweaks along the way...DML has been diligently addressing the different types of variants and is close to being done with the run, so that's why you see a lot of economy of scale with the sprues and molds. And yes, it does mean that the spares bin gets a nice dose as well along the way! DML is also going back and reclaiming the ground held by the Imperial series and early 6000 series short-barrel StuG IIIs with new-tool Smart Kits, which is a good thing but one that will take some time.
