Hi all,  I have a 1914 Baldwin Manualo 88/65 player.  It was the player
piano first on I ever had, and I still have it.

Because the pneumatics are mounted with the opening end forward,
there is no need for any striker and finger mechanism.  I think that is
ingenious.  There is simply a wooden extension (finger) mounted to the
pneumatic on the hinge side and as the pneumatic closes down (not up)
in front, the rear end lifts.  No additional moving parts.  The fingers
are in 3 rows as the 3 tiers go and they lift the piano action on 3
different levels by means of simple metal fittings attached to the
lifters on the action.

The manual is correct in stating that no adjustment of the pneumatics
is necessary.

There is an end stop rail and adjusters.  That must be adjusted so
that when the piano key is pressed down hard, the wippen will just
clear the end stop (use a thin cardboard or paper strip as a feeler
gauge).  When all is done, install the player action and close each
pneumatic by hand.  You may have to push the outer valve seat in with
a suitable object from the front, while closing the pneumatic, to
prevent the outer seat from closing and not allowing the closure of
the pneumatic.

Every pneumatic should close till it is almost fully closed but with
a little gap of 1/8" to 1/4".  If they all do that, you are done.  If
they all close fully, you have lifter the piano action wippens to make
up for lost motion and ware.  In that case, shim the player action up
on both sides with cardboard as described.

If the odd one closes completely, see if the leather on the wooden
finger is gone.  If not, bend the metal fitting a little but be careful
to hold the wood firmly as the centre pins can rip out and damage is
possible.

The pneumatics will adjust themselves to the remainder of the lost
motion because the weight of their moving board will just close them
a little more until the wooden finger touches the piano action fitting.
With new cloth, that may take some time though.

That's it,  Kind regards,
