Help w/Batrite Cochrane Georgia Driver Bat

[BigJJ]

There has been increasing knowledge of Batrite bats, and it continues, as more come to light, online and in hand. With regard to this one though, without writing paragraphs, it appears that Cochrane did not use 34 inch bats until later in his career 1934/1935. The "4" stands for 34 inches. There are many unspecified length orders at Louisville for him, but it appears that pre 1934/1935, Cochrane was 35+ inches. The bat logo, off-hand, I believe is about pre-1931, so just referencing length/era unfort it is not a match. "TA" stands for treated ash and is a top line of bats for the company. "40" is Cochrane's model bat, they just gave the model a number. "4" is the length again, 34 inches.
