We recently purchased an antique tagged "flour box with a dough bin", and are trying to learn more about what this piece is, how and where it was used, and what time period it is likely from. We've been able to find a good number of dough boxes online - trapezoidial wooden boxes similar to ours - which were used to store dough while it "rose"... Our box is large - about 4' in length and 3' high, and has a hinged open-top, and the dough box fits inside the larger "flour box", on a wooden rail/track where it can slide from side to side. We have not been able to find anything online similar to ours that's named "flour box" or "flour bin" or "flour chest"....So , is it in fact a flour box? Is it early American? Any info would be most appreciated...Thnx.
