Thanks for sharing that.  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.
