This is a casting control knob and two adjustment washers for an ABU baitcasting reel. I don't know the official name. These are parts that attach to the handle side. There are no noticeable scratches or deterioration of the plating, and it is in beautiful condition. It was attached to a reel I purchased used, and I don't think it's genuine. Avail also sells similar products, but the knurling (jagged pattern) is closer to the original. Photos 5 and 6 show the knob attached to a late 70s ABU 5500. The reel is not included in the sale. Please judge the details from the photos. Returns are not accepted. Old Tackle Old Reel ABU Ambassador
