I recently picked up a circa 1918-1921 Jack Fournier bat and was surprised to discover a fairly large number of small nails distributed over the head of the bat in what would have been the surface he most likely made contact with the ball. Since the bat was cracked and also has large nails around the crack I have no way of knowing whether those smaller nails were put in prior to the crack in order to get more power (like corking) or whether they were put in after the cracking just to salvage a bit more life from the bat in a non-game situation. Can anyone out there with knowledge of practices of that era offer an opinion? Thanks!
