ANTIQUE PENNSYLVANIA SLEIGH BELLS ON LEATHER

STRAIGHT OUT OF A BARN IN PENNSYLVANIA, IS A SET OF SLEIGH BELLS ON LEATHER, THE LEATHER IS FRAGILE AND BRITTLE AND UNSURE OF THE WHOLE STRAND IS INTACT BUT EITHER WY A NEAT LOT, THE BELLS EACH MEASURE ABOUT 1 1/2 INCHES ACROSS, THEY MAY BE BRASS?? THEY ARE NOT PERFECT. I AM SURE T IS QUITE A BIT OF HISTORY BEHIND THESE OLD SLEIGH BELLS. ITS 25 INCHES LONG GOOD LUCK
