Unknown model Andersen window need new sash balance

Quick Learner from NJ
I have this old window and need to get a new balance, I can't find the label or model number anywhere on the window or the frame, so I took out the balance hoping the number on it may help. I found these few set of numbers (11600-17) , (827) , (K32 1 90) , (11600A-3) , (3,335,455). Can these identify what model of sash balance I need?
