O.k., so I've searched the forum, and plenty of people have asked "how old is my Warwick with serial number XYZ" and the answer is generally - first letter (A-L) is month, last 2 digits are the year etc. But! The number on the headstock of my fretless Corvette Std. is T-1000001-02. I guess this means it was made in 2002, but what's the deal with the letter/number? Any thoughts?
