The pack contains 5 sprues as the one below
Each sprue contains enough parts for 1 tank with the possibility for 4 variations. These are the Panzer IV ausf. F1, F2, G and H (ausf. H is the variant with Schürtzen).
The tank is quite easy to assemble and a full assembly of the ausf. F2 took approx 15 mins, and here is the result.
I am quite confident that I'll be getting more of these for some WWII gaming.
