This bat went for $1100 in Goldin's last auction. With no length indicator after the model number of 13 and such light stamping on the "Steel Temper", it's gotta be a store model right? I've also attached a link to the MEARS article on Batrite that points out what indicates the store models. (The misspelling of Heilmann as "Heilman" is on all of his Batrite bats so that's not really a problem w/r/t this question.)
