Craig Biggio Game Used Bat Question

[cjosefy]

Please take a look at the attached images.

This bat may be the one referenced in this post:

Although there is a picture of Biggio using a bat without a model number, I'd like to hear others thoughts in this. Also, the "7" on the knob looks inconsistent with the way I've seen "7" written on other Biggio bats (and Berkman bats for that matter).

Any thoughts are appreciated.
