I have a 48-note Style 2 Piano Melodico by Giovanni Racca, circa 1906.  It is totally missing the dampers mechanism.  I have seen the mechanism but have no dimensions nor how exactly it connects to the piano action.

I am hoping someone can help me with this information so I can build one.  I have read Christian Greinacher's article, but it does not go into any detail on this part of the instrument.
