I posed this question earlier to Rich and he wasnt sure ,59 kodiaks,is there a relationship between the tip colors and the month of manufacture?I have a few that have a 3 layer tip with aBD serial # and the rest have a 5 or 7 layer i cant tell which, and they are BB or BC and I have seen a few go through with the 3 layer that always were BD or later,I was under the impression that BA BB BC BD etc indicated the batch designation or month or week but they were numbered in that order and first letter indicated lenght ,I have one that says BG but its a 7 layer tip and front that seemd to indicate early manufacture but the serial #indictes otherwise ,just curious because I thought all were 3 layer tips after the 3rd month D designstion or if you have seen a variance in the tips even in later 59 s, also what does the letter below the poundage indicate it says L ? also I noticed the string grooves are not cut into the wood lam like all the others i have, except the 56" er Is That unusual? I am sure there are a lot of 59 out there and I am courious as to what is out there.
