Re: Winston IM6 serial number 85000's ?
Winston started rolling there own blanks with # 43,500. They used the same tapers as the IM6 rods previously produced. Although the exact same tapers with the IM6 and later WT rods the rods after they started making there own blanks are definitely faster rods I own rods before and after that 43500 number in both 5 and 4 weights and they are different . If you want the older IM6 design you want rods with serials before 43500. The names were changed to WT some time after Winston was rolling there own blanks. Hope this helps.
