What do you intend to do with it ?

If it's just to make a replica for a static display, go ahead (though there are less expensive ways to go). If you intend it to be a usable component... don't put your hopes up too much. I had such a request for a turbine 1st stage : I refused as there was no way for me to ensure proper balancing, tolerances to the casing... For an external water propeller you won't have as much issues probably but you have to be reaslistic as to what this allows you to do.
