This company marked and sold tools it did not manufacture in addition to its own lines. The "Est. 1842" date probably refers to Wilkinson's own start, though it's unclear when "& Co." was added. Patents they made include a draw knife with an 1895 patent, several micrometers patented between 1883 and 1886 by Merrick M. Barnes, the rights to which were later bought around 1890 by Brown & Sharpe.
Various straight and curved configurations of the full maker name, with or without "& Co.," city, state, "MAKERS," "2 WASH ST," or "A.J.W. & CO."
Considered one of the best manufacturers of adjustable draw knives in the early 20th century, examples of their craftsmanship are common occurrences in New England tool collections.
