Shirley Kysilko of St Paul and Dick Sorensen of Minneapolis manufactured four sets of double flanges for a pre-1900 Knabe upright. One set was installed in our personal piano and is functioning perfectly. The other three are available for sale. These flanges are bushed and pinned and ready for spring installation. Shirley and Dick believe that the purchasing technician will want to make their own decision about size and weight of spring. These flanges are not the same as those in the KS Piano catalog, which have the spring and damper arm mounted on the same pin. These have pins for the hammer butt and damper arm and the spring is installed on a separate cord like normal damper flanges. If interested, please reply to me directly. Pictures are available on request. Shirley will be happy to answer any questions. Thanks, --Tom Kysilko, pds at visi.com
