Yes, I've read this quote as well. Of course it tells us absolutely nothing about how heavy any individual set of hammers might have been. It also tells us nothing about their physical characteristics: how dense they might have been, how resilient they were, etc. We can be fairly sure they were cold pressed so we can assume they were probably softer and/or more resilient than anything common today. But even this is speculation. > > Steinway uses 18 lb felt. today.. > And this, also, tells us very little about their characteristics. I read several years back of a Japanese company using "29 pound" felt on thier concert grand hammers. If this so-called specification actually meant anything the piano using these hammers would have been unplayable. As it turned out the hammers were pretty typical of most any Japanese concert grand.
