Stanley No. 21 Combination Square

Offering this nice clean 12" long blade combination square, with a nice inch graduations on both side of the blade. The blade can be mounted in 4 possible direction by loosening the blade fastener nut and moving the square head all the way to the end of the slot in the blade. Once at the end the blade can be removed or it can also simply be rotated to the opposite position on the head. The blade is very clean, with inch graduations on both sides. It is marked by the maker, "STANLEY NO. 21 PAT. 1-23-17" on the blade, and also marked "STANLEY SW MADE IN U.S.A." including the sweetheart shaped logo. This is a Christian Bodmer's patent. So this is the older 1917 patent type. In 1934 the new patent included a level and a stow-away scriber. The blade has some minor staining or darkening of the finished steel surface, but the graduations are clear and easy to read. The is a good working combo square. It has been tested and found to be very square using a precision gauge. Overall good++ condition, with about 85% of the original nickel plating intact (the nickel plating isn't as bright as when new). The square head is in nice shape, minor wear, no damage. It square has been tested to be sure it is square, looks fine! Still a nice looking tool.
