Wanted: Personna Precision Plastic Handle Shaft

I have recently purchased a used Personna Precision. Not the one pictured but a nickel plated one. All the metal on it is in really good condition but the plastic handle/shaft is in poor condition with at least one crack. Does not affect it's proper use but I would like to find a replacement. I'll consider having one machined from stainless if I can't find a replacement and then it will be a totally unique tool. But I would rather it be original. So...... anybody got one?
