Hi Andy, ive managed to get the pictures but they are a little fuzzy when you zoom in.
The E-Number is ***** one starting KS3, at the top right of the image.
Looking at the second image showing the hinge, there isnt any real solution to this, the best way I would suggest a repair if your keen on keeping it, would be to fix a new mounting for the hinge inside the door, using something like hard wood, then bolt it in place, this wouldnt be visually pleasing, nor likely to last more than a year, as the doors arent very solid, and due to the damaged bottom hinge the top hinge has probably been weakened.
In terms of acquiring a second hand door, I have had a look and certain in the south east I couldnt find any fridges of the same model going cheap to make it effective to swap the door out.
For this reason its looking like this is beyond economical repair.
