My 1919 upright Chickering Ampico does not have a cutout block that
is pictured on the tubing diagrams I have as "Figure H."  It appears
that this piano did not have that block, and I am having trouble
tubing the reroll, repeat, switch, etc.  Does anyone know another way
to tube an upright without that block, or does someone have an extra
one I could purchase?
