Blüthner with una corda

[Richard Brekne]

Hi JD

 From the looks of the two pics... it doesnt look to me like it would be 
alllll that difficult to retrofit most any piano with an una corda. 
Certainly separating the damper rail would be easy enough... The 
sideways shift could be accomplished in a number of ways since the 
actual required movement is small... you dont have any pics of this from 
the piano below do you ?

Cheers
RicB

    without any extra expense but apart from Blüthner in the old days I
    know of no
    other maker that did this for an underdamper action...These actions
    are very
    easy to work on and regulate, having the added advantage that the
    hammers are
    screwed on at the back, as in an overdamper action, so they are easy
    to remove
    without touching the levers.

    I remembered this morning that I recently took some pictures of one
    of these at
    a colleague's shop:
