Some models that I get are just too worn or broken to be retained as originals but rather than discard them I try to bring them back to life with various spare parts and a fresh coat of paint.
I am not trying to restore any model, merely make it something someone might like to display again.
This, however, is close to a restoration as it seemed the right thing to do with this one. The siren is missing on the roof but otherwise this is a nice example.
