There's a discussion over on the HAMB board about this engine, started by the guy who bought it. He said the seller told him it was last run in 1963 in a lakester at Bonneville named the Baby Whale, owned by Ron Benham. With Burke LeSage driving, it set a speed record of 213.747 mph on August 24, 1963. There are some additional engine pictures posted over there.
