A lot of pianos have this. Check the spring strength and you’ll see it’s substantially stronger than all the others. It helps keep the lifter rod from rattling when at rest. Why does this old German action I saw the other day, have an extra damper lever complete with spring, but no damper, and where none could go? Is it to apply a tiny extra bit of pressure to the damper lift rod? I dunno! David. -------------- next part -------------- An HTML attachment was scrubbed...
