Should reach the shelves right now this new Elefant from Tamiya in 1/48 scale.
An upgrade Zimmerit set is available apart.
From the Tamiya site:
★Packing a fearsome 8.8cm gun and protected by armor up to 200mm thick, the German heavy tank destroyer Elefant appeared in the latter stages of WWII in Italy and on the Eastern Front. ★This precision 1/48 scale plastic model assembly kit faithfully captures the Elefant's form. ★Fighting compartment parts breakdown is based upon the weld lines seen on real Elefants. ★Comes with a commander torso figure to up the realism even further! ★Weights for installation in the hull give a realistically heavy feel.
