Steve: As Daryl said, the Flues model was made from about 1915 to 1921, and will have a serial number below 398,000. The 'Knick' was an entirely different, and much stronger, design with a serial number above 400,000. The Flues tended to crack around the forend button (I had a Victory grade with that) and the cocking lever would break (and had a 4E with that).
