This one is fully enclosed. This a sig artillery gun mounted onto panzer 3 chassis. Also put some rust touches on it...from err... stone chips lol.
And put some crew on these ones. These two are the same gun on panzer 1 chassis. Did one with the wheels inside the vehicle and one with them on the front...as per actual photos from Mr. Goggle.
All of these were used in and around Stalingrad...
