Dave, Sorry I can't answer your question. I'm responding only because I tuned a 1925 Premier grand a couple times, and I felt the piano's life was over. But pianos are very different, of course. What is the condition of the piano overall? Is it owned by a client or by you? Depending on what gymnastics you have to go through to repair the problem with the action brackets, you might have to question whether it's worth doing anything at all.
