I am rebuilding a Kaps 88-note player piano and seek information about
it and parts for it.  The tracking device is marked "Kastner."  It has
double-valves in metal housings, one for each note.  Some are missing,
and I need to replace them.

Is there somebody around the world who has, or makes, such valves?
Does somebody even know whether what I have is a Kastner player
mechanism?  Any background or history on what I have will be much
appreciated.

I am attaching some pictures of the valve parts.
