There are obvious characteristics in the stamping that show me this is transfer type of application. The ink quality is not typical of stamping that was used for that 1934-1939 model, it shows dotting and inkjet characteristics. second, it is not at all crisp like genuine models, even worn stamping is still legible and crisp even if its faded. Third, in the bottom logo from the pictures you posted, in the "Cushioned Cork Center" stamping, the "K" in Cork, and the "C" in Center are touching and nearly on top of each other. This is what happens when a transfer type of stamp bends to the curvature of the ball whereas the sheet or transfer is flat, and when pressed onto a round surface it causes it to bend and overlap (think of when you used to use patterns on paper to carve pumpkins). Fourth, The ball itself is worn only behind the stamping areas, this is done so the ink doesn't bleed, but it's a complete giveaway. Look at the "Q" in "Quality", it has bled because the ball was too slick in that area to hold the ink. This would never happen with the metal stamps and ink quality used in that era. Also the leather and stitching are not consistent with that model ball.
PS, did I mention my authentication service yet? lol
