Matthew, I assume in this test you were attempting to eliminate the wippen flange as being the cause of the sluggishness. You may have done this and didn't say it in your post, but you also need to disconnect the bridle strap and hold the hammer assembly towards the strings as well as holding the key to feel sluggishness in the wippen flange when you lift it somewhat up and down. Aside from this test, most likely you have a key weight problem, especially if you do determine the flange centers and the key bushings are basically free. It is not an uncommon situation in some Wurlitzer vertical pianos. Also, nested bushings are very possible as the angle of the keyarm can be quite severe in some of these pianos in the treble section. Sincerely, Keith
