Certain Teed window spring/balance

A quick learner from PA says:
Hello,

I have a Certain Teed window, 32 x 53. The store that use to supply me with the spare parts no longer does. Attached is a picture of a similar spring. Other numbers on the tag are:
28325 - 26.19 61-13 - stop.
Please let me know if you need more information for a replacement part.

Thank you for your help.

Regards,

Joe

Thank you for submitting your photo, Joe. Are there any numbers on the coil balance itself? We will need the number printed on the balance spring in order to identify the correct replacement.

Hi Paul,

Thanks for getting back to me. I took out the broken spring and found 335 J on it. It looked like it was etched or scratche in by hand. I removed the good spring also. That had 335 J stamped on it. Which do you recommend I order? The window is 32 x 53. Thanks again for your help.

Regards,

Joe

Joe, have a look at the S170-335 Coil Balance.

Sorry Paul. I did not know to continue on this same thread. The good spring had 409 stamped on it, not 335. So, it looks like I have 2 different springs, which seems odd. I will try the 335 unless you advise me otherwise. Have a nice weekend.
