Hello!

Some asked to see pictures of teh una corda system of my 1860 Pleyel  
upright
piano, so here they are.
The mechanism is quite simple:

The left pedal pushes (via linkage) a metal rod up, located on the rigth
side of the piano's case. This rod has a piece of wood covered in  
leather at
its top. It pushes on a bronze L-shaped piece (screwed to the action  
frame)
which turns the up-down movement into left-right movement. The L-piece
pushes rigth against the end of the hammer rail which in turn moves  
to the
left.
The hammer rail is loosely connected to the action frame at its ends  
(via
bronze gliding pieces, that bear on pieces of felt).
A leaf spring (on the left side of the action frame) pushes the  
hammer rail
back in normal position when the pedal is released.
