So the label pinpoints it to the 1980-83 area, and the 35" length (and absence of an "8" on the knob) would indicate a team index bat, as he was ordering 34 inch U1's at the time. The only usage evidence that I found on it that points to Stargell is the seam indentations on the side of the bat that lefties would hit with with the label up. Anyways, it looks like it had some light/moderate usage, probably in practice, since this is most likely a team index bat.

Is there any record of how many of this model was ordered for index bats? And what is the approximate value of this piece, in your opinion?

Thank you so much for your help on this.
