Looks like a Sherman Firefly.One of those killed German tank ace Wittmann and his whole crew,17pdr shell penetrated the turret armour and set off the ammo.
Ahhh, a fellow Wittman aficionado. I built so many Tiger/Wittman models as a child. You know, there is a bit of controversy as to what or who blew him up.
BTW, in my Marine career (1981-85) I was a TOW missile man. I used to fantasize about having a Tiger, Panther, or King Tiger in my sights. T-34s were too damned ugly.
