Vintage ball and Boxscore

[yanks12025]

So I picked up one of the Rube Walberg balls from ebay. And was wondering if anyone knew how many balls hey used back then And if someone can read this boxscore to see who made the last out. I think it's Don Heffner but not 100% sure. Ball is from a game between the Red Sox's and Yankees on July 3rd 1934, best thing Ruth and Gehrig played and Gehrig had a homerun this game.
