Anderson window sash balance identification

A quick learner says:
I need help identifying the correct replacement part for this andersen window sash balance. It is for a double hung window and I need the left and right side. It looks to be 11600-17 and BR1 11435 10 84. There is a # between the 11 and 35 then a space and then 10 84

Hello!

Thanks for reaching out to us. I'm afraid these stamps don't match up to a particular Andersen sash balance. I'm going to forward this to one of our senior experts to get his thoughts on the matter. We'll reach out as soon as more information is available. 

Thank you!

I'm having trouble reading the numbers that are after the BR stamp. Can you confirm what they are? I wonder if the number 5 is another 3 which would make the number 1133. 

A quick learner says:
I looked at the other one I have and it is 33 after the #

If the balance includes the number 1133, then the 24-1133 Andersen sash balance is my pick. Take a look at the specifications and see what you think.

I ordered the 24-1133. Thanks for the help paul.
