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.
