So, the "Damage" looks more like a serious short that made the fuse get so hot, it melted the fuse holder. If you look at the wire coming from the burnt fuse, you can see that the insulation is melted away. I know SPis only but those brown wires carry the power around the car. I would be sure you are checking the wiring before installing a seemingly rare part once you find one.
Looked into this closer and this is the fuse box at the very front of the engine bay, correct? In front of the brake master? Did they have a front end collision? Maybe some of the bodywork crushed into the fuse area and caused the short that melted this?
