In step 31 of this kit's instructions, you are told to put a tiny aiming vane on the front of the turret. It's a photo-etch piece, part TP8.
But this part is not correct for any of this kit's decal sets. It was not used on any Tigers of this version, as far as we can see.
Some of the first Tigers in Africa had this vane, but it doesn't belong on this version or in this kit. You should not use it.
