Another variant of a bunker for a static panther turret. This variant is larger than the one posted before and required more construction material. The turret itself had no steal basement but was inserted directly into the bunker notch. While this big variant is a 'standard construction' the smaller variant is a 'special construction'.
I guess the smaller variant was introduced to match with the simplified and improved production technics. With the turret already mounted on the gearing(?) it could be sat on top of the bunker without having the need for complex technical knowledge.
Unfortunately I do not have any satisfying pictures except this blueprint.
Finally: proof that necessity is the mother of invention.
