Andersen window balance J15 5423 385.

A quick learner from Halifax, Pa says:
My old andersen window balance numbers don't match anything you have listed. The numbers I find on the old balance are;
J15 5423 385. I also see another number 11600-17. They are on the side with the pull ropes. On the other side there is a number 11600-3, there is also a date 1967 Can and the pat. number 3.335.455. In appearance it looks just like any one of models in your display. The measurements are 6 1/4" long (not counting mounting strip) 2 7/8" wide and 3/4" thick. Thanks for you help.
