The older Wurzen quality derives from when the former Weickert factory=20= was taken over and was called the Wurzen factory in the early 90's. As far as I understand it, the Wurzen factory today sells two kinds of=20= Wurzen felt : regular quality and AA quality. Renner is one of the main buyers and makes most of its hammers with=20 Wurzen felt, Abel apparently has a reason not to use it, Ronsen now=20 also sells AA quality but mainly (again, as far as I know) to Canada=20 and the USA. The other hammer makers are either piano factories like Yamaha and=20 Samick or hammer makers which are still not big enough players on the=20 market to have a real name. So you might say that, probably, only Renner and Ronsen sell Wurzen=20 covered hammers. It is up to piano technicians to make their choice. In the future I will try to block my "visual=A0cortex" so that nobody=20= will be bothered by any "delicious foodstuff"s.
