need a little help with a Hank Aaron bat

[kcgranola]

any help would be great.

I bought what I thought was a Aaron store model bat today at a antique shop. I was wondering if anyone had any info on this type of bat as it is not a little league bat and has the 125 and geniune logo on the bat. I will have pictures up in a bit but any help would be great. the knob of the bat has a capital HA3 stamped in it.
