Answer 1

The Tony Oliva Louisville Slugger 125LL you have is a store model Little League bat. The dating of the bat is one of the most important factors on value along with condition. Hillerich & Bradsby Co. Louisville Slugger has used different oval center brands in their history. By identifying the center label, trade marks, and patens you can narrow down the year to what era the bat was made.

For example: a bat made between 1916 - 1929 will have HILLERERICH & BRADSBY Co in the center label as opposed to J.F. HILLERERICH & SON Co as the bats made before. TRADE MARK REG US PAT OFF appears below the oval and changed to TRADE MARK REG in 1930.

The "Flame Tempered" is the lower grade version of "powerized" that appears on Louisville Slugger Bats. It's a process to harden the surface of the bat.
