I can't tell from the autograph, but one Ken Hunt was a pitcher for just one season, so I'd doubt he'd have a contract with H&B -- he probably used a block-letter bat. The other Ken Hunt was a position player for five seasons -- I'd put my money on him.
Does the bat have a uni number on the knob? The pitcher wore #41. The other Ken Hunt wore #44, #26, #20, #6 and #12 during his career.
