So I have been able to determine that I have a 770 Series channel balance that is 23" but can't determine the weight rating on it. Can you please assist.

Hello,
I agree that your balance looks like our S770-23 but the stamp is a bit out of the ordinary. I'd recommend weighing the window sash and following the chart below from the S770-23 product page to confirm the correct strength option. Thank you!
Stamp Option Sash Weight Range
A 5 to 10 lbs
B 10 to 16 lbs
C 16 to 21 lbs
D 21 to 24 lbs
E 24 to 27 lbs
