Doesn't look that bad. It always amazes me why some idiots want to display tanks with the gun to the rear....Ours had the gun welded into the travel lock and it took our shop a week to get it loose and some of the weld scars ground off.
As Panther F wrote, the tracks are OK. Very unusual is the sledge mounted on the turret. Most of the pioneer tools are left off as they get stolen any way.
