Check out a website Shotgunworld.com lots of info like this:
The "New White Powder Wonder" was made by the Crescent Fire Arms Co. if produced before 1919 and by the J. Stevens Arms Co. if it was made after 1919. Single barreled shotguns, such as yours, that are so marked were made by the W. H. Davenport Arms Company circa 1891 to 1910.
The trade name White Powder Wonder was used by a number of companies. It was used by the Cescent Fire Arms Company, The W.H. Davenport Arms Company, The Meriden Fire Arms Company - Fyrberg type single, and the J. Stevens Arms and Tool Company who produced them for Sears, Roebuck & Co.
