No real instructions, just a single drawing showing all the pieces, but not the best order to assemble. The hint I would give is to glue the hull top and bottom together first and then put the track and wheel assembly in place. Otherwise, the track may not fit properly. Also, no decals are included, so you will need to buy them or paint your own.
If you hate connecting or building AFV tracks, you will love this line of kits, as the wheels and tracks are a single piece molding. Was disappointed with the lack detail on the wheels, on the Pz III the front and rear drive and idler wheels have multiple lightning holes in them. In these models, instead, you get a molded hint of these holes. I was able to drill them out using a 1/16th drill bit which greatly improves the realism to me. I tried using a micro-sized bit to drill out the roadwheels, but decided the effect wasn't worth the effort and broken drill bits. :-(
You get some extra pieces (side armor & rear turret storage box) that are used in other versions that obviously use this same hull and track mold. You may be able to use them on other kits you have. Turret rotates and gun elevates.
Quick and dirty, about 30 minutes to build and paint. If you want more accuracy, perhaps a weekend project to sand, dry and weather. Worth the price.
