Yes it is. A good friend told me about it or I would have missed it. By far, it's one of the nicest of maybe a dozen 4500HP "baby" turbines I've owned over the past 30 years, including a very smooth running re-powered unit.
I bought this turbine for it's looks and thought it would be a display piece only, so you can imagine my surprise when it ran smoothly and quietly, which is not a trait of stock OMI "tank drive" turbines and like another unpainted "new" standard turbine I own, it's a real clunker.
