A few interesting things: 1. What I at first took to be a novel wippen assist spring appears to be the repetition spring. 2. The repetition lever is not actually rotating about the wippen center, as on a more typical action, but is rotating about its own center. So, some of the mass of the repetition lever is not being supported by the capstan (probably insignificant), and there could perhaps be a little bit of relative movement between the underside of the repetition lever and the top of the jack as the action moves through its range of motion (probably also insignificant). 3. It's not clear to me what the top of the jack is acting against. It appears to be a slot in the end of the repetition lever. Does the underside of the slot have a piece of leather on it? It's not clear to me what advantage one would obtain by having the jack act in this slot on the repetition lever rather than directly on a knuckle, but it would appear to have the disadvantage of reducing the feeling of direct connection between the jack and the hammer shank. 4. There appears not to be a drop screw, or its equivalent. It would seem that if you weren't careful about setting repetition lever height you might end up with almost no letoff feel. Not a good thing I would think. Phil Ford ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
