Hello! Your balance appears to be a match for our S770-28. Look it over and see if you agree.

The balance comes pre-assembled and ready to install out of the box. The only component sold separately is the pivot shoe, which is our 15-129. You may very well be able to just reuse the original, since it doesn't appear to be damaged.
