An Antique 2" Inside Dia., Cast Iron Tenon Spoke Pointer Chair Brace Tool.  There is no maker mark on the tool.  The 1-1/2" cutter is sharp. Tool stands approx. 5" tall.  NO cracks, breaks or repairs. On the inner wall, there is a hole where the lower cutter screw is. Not sure if this is a defect or just part of the overall casting design. Either way it has no impact on the tool's functionality. Please review pics to confirm condition!
