I have a 1911-16 Hillerich & Son 40 L. Louisville Slugger with no decal. It's 34.5 ins and about 40 oz. I know the L stands for Lajoie. What I don't know is whether a 40 L. bat can ever be considered a pro model. This bat pretty much matches Lajoie's bat stats and I believe it's too heavy for a store bat. Also, are the 40 D. and 40 B. bats of the same era Hugh Duffy and Pete Browning models. Thanks for your help. Ron
