to me the wood of the bat does not look like pro model wood.

bat records also do not make sense. I have a bat with the signature of Frank Murphy on it. It is a pro wood bat with no center brand just the name in signature script of Frank Murphy with Trade Mark at the end of the barrel

Now there was a Frank Murphy who played MLB in 1901, but that would be pre Wagners endorsement deal. One other Frank Murphy who played minor league baseball in 1914. Problem was he was only a class D player in the Staten Island League, so why would he have an H&B type signature model bat. Makes no sense unless he asked for some to be made and paid for them himself and H&B or who ever gave him a choice of what a bat would cost. A pro bat wood would be this, a store model bat wood be that.

So it is possible in this case a Mr Jackson asked for some bats and asked for the store model wood. This would also be the same in the examples in Bushings article.

not far fetched
