Thanks for the pics.

You might be looking at a rookie era bat. Can you measure the centerbrand for me fro right to left in inches? This can determine year.

As far as game use... I cannot read any knob markings, and don't know what the white substance is that is on the knob. I would have expected to see a magic marker 18 written and nothing more. I am unable to see the rest of the barrel for actual use, and also the tape job is not as expected for a Strawberry bat (I have only seen tape used on a couple of his bats, much later in his career, and applied differently).
