Help Identifying Souvenir Louisville Slugger

Hi. I’m new here so hopefully this is in the right spot. I recently was given an old 125 Louisville Slugger mini bat by my father (72yo). He said he remembers playing with it as a kid and that it was my grandfather’s from when he was a kid. So “very old” is all I know but I can’t find any info on this specific logo with the TRADEMARK in the middle and Made in USA underneath.

Maybe an old knockoff?

Also there’s an odd knob shape:

Any help is much appreciated. Thank you.
