What type of bat did Mickey Mantle use?
Some of the baseball bats Mickey Mantle used included Louisville Slugger Models M110, K55, and P72. Hillerich & Bradsby began making K55 bats in the 1950’s.The earlier H&B professional K55 Bats had K55 written on the knob. Louisville Slugger started putting model numbers on the end of the knob in 1943. If you have a Mickey Mantle Bat with K55 on the barrel you have a store model bat.
