Schmidt game used bat characteristics

[emann]

Does anyone on list know if Mike Schmidt used the Adirondack model with "1980" stamped into the knob? It's a model 300, 35"... It seems like that might be a retail brand (maybe from the following year?), but need some help... I did a little research on here and know he used the M520, 154A & 256X but nobody mentions "1980". Also what are some other bat characteristics to look for (where did most of his ball marks usually land, etc)?

Thanks in advance for any answers.
