I've checked the Hamilton/Wadsworth Case data base trying to determine when this "Ball Model" case was made. The Serial Number sports the "V" orientation but it begins with a "7" and is 7 digits long. Anybody able to tell me when this Ball Model Wadsworth/Hamilton case was made? Serial Number is 7566861. Data Base says they begin with a "0" or J, K, H, etc. What am I missing?
