I agree with Cheapshooter. If your Fox Model B is falling apart when you shoot it, it's because something's wrong with the mechanicals, not because it was made to fire only a couple or so boxes of shells a year. Even the cheapest American-made single-shots made during the era (i.e., the Winchester Model 37, the Harrington & Richardson "Topper" and the Iver Johnson "Champion", to name a few) were designed to fire thousands of rounds safely before needing repair.
