There could be a number of reasons why this crack has appeared...these hickory shafted clubs were,nt designed to hit modern golf balls,thy are too heavy...the balls in the 20,s were lighter,if you look on that link i posted..it tells you there,..another reason could be, that it was a bad golfer who swung the club and duffed his shot...e.g, hit the ground,...realistically, this club is,nt worth anything, bar being used for decorative purposes,
