Based on your stamp of 9 27, I recommend our 24-939 Andersen sash balance.
A home owner from Buffalo, NY says:
The unit you recommended does not look like the one in the photo. The unit in the photo does not have a tab with screw holes, it also has two screw holes in the center where the recommend one does not?

Ah, I see. It appears your balance is the older style. Andersen no longer makes them like this, I'm afraid. Fortunately, you can cut out space in the wood to accept the new tab and it should be okay.
