Please help me identify both left and right balances for the above Sizes/Model Numbers. I couldn't get a clear photo of the balance, but the existing right balance on one of the 3456 Windows has the following stamp:

BP25 12 # 27 2-88

Based on your stamp of "12#27," I recommend our 24-1231 Andersen sash balance. Check it out and see what you think.
