This is a vintage 12" STANLEY - MADE IN U.S.A. No. 36 1/2 two-fold boxwood and brass Carpenters' rule with square joint and sliding brass caliper. Plus, this example is marked with the Sweetheart trademark. I rate this ruler in GOOD CONDITION overall. It has the alignment pin and folds up nice and tight. Most of the numbers and markings are clear and easy to read. Uncleaned with a few minor stains. A nice example of a vintage Stanley folding caliper rule for you to add to your antique measuring tool collection or put to use in your workshop!
