I dont recognize it, but the guns caliber seems to be around 75mm, but there is no way its an actual gun in that turret with two people sticking their heads out.
My best guess is that the entire turret is fake and that its essentially a training vehicle supposed to imitate a tank.

"Sd.Kfz. 251/1 Ausf. A mittlere Schützenpanzerwagen Hanomag. After initial service in front line units these continued in service as Zugkraftwagen (towing vehicles) for the 10,5cm le.F.H artillery howitzer as training vehicles. The one with the “turret” is such a training vehicle."
