Weigh them and write this on the molding. Place them on a flat bed scanner and create a full scale image. This would give me a good idea of how dense the felt is. Just to be sure you could scan a ruler along with the hammers. Check out the drawings in the new Renner catalogue page 1-15. They are to scale and yes they were shaped this way. The number one hammer of G3M or G4M weigh about 11 grams. Hammers from earlier N.Y Steinways are about the same size (often even a bit larger) but weigh only about 8.5 grams. This indicates a big difference in felt density.
