Hello all.  We have nearly completed the case and action work for our
1919 Hamburg Steinway-Welte "O".  As we are about to begin the work
on the Welte action, we are still in need of a little help.

We are missing a few minor parts, which will be easy to duplicate
if we know a little more about them.  Missing are the blocks to which
the expression lock and cancel mount to.  These we assume are very
similar in design to the block for the pedal lock and cancel.

If anyone might have a diagram as to which tubes match which holes,
this should be an easy item to copy.  We are also missing the block
to which the expression pneumatics mount.  This seem to simply need
a connection to vacuum supply and to each end of the stack.

Does anyone have schematic for these?  Also, does anyone have photos
of the underside of a Welte Grand with all the pneumatic parts in
place?
