What is the year model of a King Nitro 12 gauge serial number 24195?

This was a trade name sold through Shapleigh Hardware of St Louis. If it is a single shot, it could have been made by W H Davenport Arms c. 1900-1903 or Iver Johnson Arms and Cycle Works c. 1904-1950. If a double barrel with outside hammers it was probably imported from Belgium c. 1900-1914 or made by J Stevens Arms c. 1920-1950.
