The old Steinway uprights I've seen had a metal sost. rod covered with fabric.
Haven't seen the 'taut gut string' described yet. Re: Haddorff, it's listed in 
my Michel's Piano Atlas of 1949. If I recall what I was told correctly, Mr. 
Haddorff committed suicide (in his factory?)              Jonathan Moberg, RPT
