Obtained from the son of a 1930's Spalding salesman who took these right out of the factory and home one day. Complete set of irons are in gorgeous NRMT condition. Wood shafts (a bamboo look), the clubs are marked "Kro-Flite" with "Robt. T. Jones" facsimile signature engraved in the metal. They each have a Reg. Number in the leather of what appears to be CJ104025A. They are a complete set numbered 1 thru 9 and look ready for the Augusta National. They were described to us as prototypes of some kind, but we are selling them as old original and as what they are.
