Greg over at the uber-blog Petch House pointed out in the Old House Web forums that there’s an 1888 J.L. Mott Iron Works catalog online at the New York Public Library Digital Gallery. I have a reprint of a 1914 Mott catalog that I oughts to scan and put online. In the meantime, check out the 1888 flushing-rim slop sink:
