CLARK’S O.N.T. 6 drawer Spool Cabinet

I found this Clark’s O.N.T. Spool Cabinet about 5 years ago in an antiques store. It is in overall great condition with all the trim intact and looks to be made of walnut. It has a slanted writing surface with the original paper/ leatherette covering. Six drawers retain their original stenciling and pairs of brass pulls. The top lifts to reveal storage. I imagine it having sat on a counter in a dry goods store with the logo badge facing out toward the customer. I’m dating it circa 1900-1920, but would welcome anyone’s input with knowledge of these great old store fixtures.
