Mike,
The Lindberg kit is not the Frigate of 1797; it is the Sloop-of-War U.S.S. Constellation, built in the 1850's that was "altered" in the 1950's to convince the public that she was the original Frigate. The ship has since been restored to her correct form, to represent the Sloop. The Sloop-of-War U.S.S. Constellation was the last sailing ship built for the U.S. Navy, whereas the original Frigate U.S.S. Constellation was the first ship built for the U.S. Navy. They are, in fact, two very different ships. The model depicts her in the "altered" state depicting her as the Frigate.
