1961-1963 Adirondack Mickey Mantle Bat 34"-31.5oz Help
 

I'm trying to figure out exactly what year this bat is? The flame treated marking is throwing me off with the cursive "Adirondack" on the label. It looks like "65" is marked in marker on the knob? Could that be year?

I've been told it could be a game used bat but I'm not a bat expert. After reading about game used Adirondack bats, I don't believe the 288D were gamers.

Any help is appreciated.

From what I have been told, Adirondack bats with D stamped on the knob were typically used by colleges.

For Adirondack it goes:
A/B - Professional Model
C - Possible professional model and most likely team index
D - Colleges
