Rare Early STANLEY No. 13-1/2 Extra Wide Boxwood & Brass Folding Caliper Rule

A very nice example of a rule introduced by Stanley in 1888.  Rarely found marked with the early “Stanley Rule & Level Co.” trade mark, this can be considered the type one of this particular model.  Joint is good and tight.  Rule body and brass slide are both marked with the assembly number 52.  A great little rule.
