[pianotech] help needed with Hamilton

[Terry Farrell]

I replaced the damper felt on a Hamilton of about the same vintage a  
couple years ago and did the Spurlock thing in the bass with VERY good  
results. I think I made those myself, however, now I am purchasing my  
upright bass dampers from Jurgen at Pianoforte Supply - he has very  
nice bass dampers in 55 mm and 67 mm lengths:  http://www.pianofortesupply.com/dampers1.html
