That's the PzKpfw NbFz VI, produced by Rheinmetall-Borsig with a Krupp turret, Germany's last holdover from the prewar 'land battleship' school of tank design. It had a 75mm KwK L/24 and 37mm KwK L/45 in the turret and two MG13/34 in modified PzKpfw I turrets at the forward right and left rear of the main turret.
That particular tank was part of Panzer Abteilung zur besonderer Vervendung 40, serving in Norway in 1940, and was abandoned on 25 April 1940 after being immobilized by 25mm AT gun fire from the 1st Battalion of Kings Own Yorkshire Light Infantry at the village of Kvam.
