I just got my fna jazzman I ordered at the end of June. Well worth the wait. Anyway my question is about the serial numbers on the back of the neck. I realize the last two numbers are the year but I don't understand the rest. I'm asking because my guitar player about a month ago got a les paul and he could go on the sight and see when, where,it was made and even other info on his git. I looked on the Warwick and I don't see availible info. Now I did do a search first on this question and I didn't see anything but what I didn't do is e-mail Danna and ask those guys. My numbers are k-102156-03 if that helps. She is my first German Warwick I love her!!!!!!!!!
