I don't remember the model number but the Allison
   turboprops on the Lockheed Electras and C-130's turned
   a constant 13,000+ (I think it was 700) RPM. Power was
   controled by prop pitch  change. Karibian



That's the T56 Allison..  Used on Electras and still on P3 Orion, and
C130's up to the C130 (which has been re-engined with the Rolls Royce
AE2100D).
