This is a conversion turret for use on the ESCI (Italeri) King Tiger.
This particular set includes only two parts, the turret and the gun. It is exceptionally well cast, with no air bubbles or other flaws. But on my sample, the gun has pulled away a bit from its carrier, and hence it is slightly warped. As you can see, the turret is solid, and all the hatches are molded shut. But the detail is very sharp, much sharper than the TP Models Porsche turret. The turret ventilator cover is beautifully under-cut, as are all the periscope covers. One lift ring is broken off, but that can easily be fixed.
Compared to drawings in Achtung Panzer, this turret is very accurate in size, shape and details.
