Another perspective on 18th century New England nails comes from "Nailer
Tom's Diary", the journal of Thomas B. Hazard, a blacksmith who worked in
Rhode Island in the 18th and early 19th centuries.  This was published in
1930 by the Marymount press in Boston if memory serves.  For the years 1782
to 1786, the years I have read through so far, he mentions the following
kinds of nails: shingle, plank, deck, clinch, pump, shoe, cart, 8d, and
"larth" (lath ?).  He also writes of making brads, floor brads, spikes, and
shoe tacks.
