The problem about this model, is that, even it's a lovely model, he dont met the ED requierements. At least more than 70,000 faces..... Some a HUDGE simplifaication of this model need to be done.
There is no animations, so everything must be done.
Materials are not standards, and no mapping on the model, so everything must be done.
It will be certainelly faster to simplifly than to do an other one from scratch, but it will be long.
By the way, it's very kind to find some models, but it would be super, if the models you find met the requierements.
My two cents ......
