Plyerman, It is pretty much the smallest ALL METAL one they made. The so called "baby Coes" had a wood handle and was 4 5/8 in. long. These all metal ones were produced after the babies. There is also a scarce all metal variant that had a round handle with knurling on the bottom end. It was the very first of the all metal small Coes wrenches. I have never seen one of them, but they do exist.
