David About those 22 pound or 25 pound As you know it is the weight of the felt plate on this picture it was 22 pound Wurzen Grade A for concert grand it was the first plate I bring to Ronsen about ten years ago those plate are standard dimension about 41 inch square and different tickness from 23mm to 30 in bass and 3mm to 9mm in treble more tick more weight more density more weight... The New-York S&S hammer was make with low density about the same density in the treble that the bass but thick German tape plate.
