Very nice early UPSON No. 66-1/2 Boxwood & Brass Rule. 3-foot long, four-fold, arch joint. Upson Nut Co started out around 1872, Andrew UPSON was president of the company. For a while they were in the top 5 rule producers in the United States. Stanley bought out Upson in 1893. This rule is in excellent condition for its age of 140 years plus. A great piece of history for the collection. If you require any further information or more pictures, just yell out. Wait for the invoice as postage may be less than quoted.
