This kit is basically a slightly upgraded re-box (reboot) of their Premium Edition Kit 6317 that came out in 2008. The new parts are two photo etched tool boxes instead of one, a newly designed photo etched tool box to fit on the rear of the fighting compartment, different Magic Tracks specifically for the Kursk campaign, and a new set of decals that are supposed to allow you to build any vehicle that served with the s.Pz.Jg.Abt.653 or s.Pz.Jg.Abt.653 units at Kursk.
This is a multimedia kit comprised of 270+ styrene parts, magic tracks in the early pattern, three photo etched frets, a turned aluminum gun tube, decals, and the set of instructions that need to be reviewed very carefully before gluing any parts together. Most Dragon models today are a collection of old sprues with new sprues added to create a new kit variant, and Dragon has done so with this kit.
