Don't quote me on it - but there is a chance that the dryer is actually a DE-750W (on my Mac it almost looks pink!). The model tag certainly looks like that from an electric and not a gas, possibly making it a water/condenser dryer. But, since it has been out in the elements, who knows what long gone NOS parts it needs. The only way to know for certain is either a pic of the model tag or a picture of the back of the dryer.
