Hi Ed, Before you go through a lot of work, pick the worst two side by side notes. Remove the 3 lengths of string, polish the pressure bars with emery paper, restring and evaluate. You may be able to steal a couple of thou of down bearing by tightening the plate bolts. If the hammers have been reshaped, the C7's take quite a bit of needling to get the tone to sing. Usually this model responds extemely well to steam, high on the shoulders. Just a thought?
