This Vintage Roberto Clemente: 1969-1972 Hillerich & Bradsby (34”, 31-oz) Baseball Bat has been used and does have a cracked handle. It could be repaired with tape (had tape on it when I bought it). Has BC4 on base of handle and all writing is legible. There are no dings or divots in this bat- surface is smooth. The number that appears in the center brand is the catalog number, used to order bats. The "125" is the catalog number designated for Professional and high quality store model bats. The highest grade of wood is reserved for all 125 baseball bats. Before the 125 the No. 40 was the highest quality line of baseball bats in the Louisville Slugger catalog. The 125 is not the model number. Louisville slugger began using model numbers on the knob in 1943 then moving the model number to the barrel in 1977. The "Powerized" process was patented by the Hillerich & Bradsby Co. in 1931. They introduced the "Powerized and Bone Rubbed" logo for the 1932 season. "Powerized and Oil Tempered" was only used in 1933-1934. H&B also produced bats in 1933 & 1934 stamped "Trade Mark Reg U.S. Pat Off" under the center brand with "Powerized" alone. Beginning in 1935 until present, "Powerized" is used exclusively. The Powerized" process is to harden the surface of the bat much like the bone rubbed finish of the 1920's. A 1938 Louisville Slugger ad states: "'Powerizing' is a treatment by a special patented process that reduces chipping and peeling to a minimum, increasing the driving of the bat and prolongs it's life."
