[Refugee]

What a nasty accident.
Resin can be bought from a boat builders. They also sell coloring stuff to add in order to get a match with the original case. The colors should also work with car body filler. It will need to be put together dry first so that a sequence can be worked out before using the resin to fit it all back otherwise you may get bits that will not go back in. It will have to be done in several sittings by the looks.
There will almost certainly be little bits missing and i am not sure if the dyes will work with Araldite without doing an experiment.
