Cincinnati Tool Company No. 600 Clamp Fixture

I recently picked up this pipe clamp fixture, still in its original pasteboard box with metal reinforcers at the corners.  It's amazing that the box has survived over all of those years.   Anyway, I've never had the opportunity to open an original box and actually lift out a never-used tool from decades past.  Very cool!  The clamp is now installed on a long 3/4" pipe.  Until I saw the drawings on the box, I had thought that the Cincinnati Tool Company only made clamps.  I hadn't realized that they made striking tools as well.
