I have a set on the shelf at the shop. A guy gave me a set, and wanted me to try them, maybe 10-15 years ago. These were a dense, springy foam, at least when new. He thought they improved key return. I would bet that he used them on the actions he rebuilt. I never did try them. Easy enough to replace I guess.

Hi folks. I don't post much but enjoy your musings ! I thought I'd seen most things, but ran into these on a Steinway M. Quite a surprise. Foam punchings. Holding up pretty well it seems, I don't know how long they've been there. Pretty mushy, I won't be leaving them. Stop gap work while they raise funds for a new one. Have I been under a rock?!
