Very small size. I can see the faintest hint of an arched maker's stamp which is HALL & KNAPP as 'KNAPP' is visible in the right light. Rosewood and brass in nice condition. Some pitting on the blade. Very uncommon maker and size.
From Eric Benson (https://chapticowood.com/pages/early_american.html) who has done tremendous work on documenting early square makers: Thomas S. Hall & Frederick Knapp started their company in 1853 to produce squares, bevels, and levels. In 1858 it merges with A. Stanley & Co to form Stanley Rule & Level. Since A Stanley & Co produced rules, the combined products of the two companies were a perfect compliment. The squares and bevels produced by Hall & Knapp therefore became the early offerings by Stanley Rule & Level.
