SWISCO - The Replacement Hardware Authority

~25 year old wooden Andersen window balance

A home owner from RI says:
I can clearly make out 11600-17 on the associated photo. A search through your past posting indicate that's not really helpful, though. There is what appears to be a "576" stamped on the opposite side, but that doesn't appear to match the codes on your site. So, I was hoping you could either

1) identify the part by seeing something I'm missing or

2) let me know where else to look for stamps/markings.

I didn't want to remove the part yet because it is holding up the upper half of a double hung window.

Hello! The key stamp here is on the bottom. I've provided a picture here of it blown up.

I can just make our "9#27," which is exactly what we need. If you can confirm, I'd recommend our 24-939 Andersen sash balance.
A quick learner says:
Tom, thanks for the quick response. You can add "eagle eye" to your profile. I had hard time reading the numbers off the original ... even just inches away. It does, in fact, appear to be 9#27. I'll be placing an order shortly. Thanks again for the assistance.
