Next to last we have a compact, though not really small, lady that was built for Air only operations. Many, but not all of Wolfgang Engineering's fleet of turbines, were built to be steam capable, but these last two sisters were not. Tangentially fed up front and tangentially exhausted to the rear after 270o of rotation, she is capable of hitting some really high notes if provided with enough volume and pressure, as she is rated at 60,000 rpm, though just how that rating was derived is outside my knowledge base.
