I am pretty sure John Tuttle of Player-Care is having switches for the
Model A Ampico made next year.  They are very time consuming to make
from scratch; treasure the ones you have!  From what I understand he
has a few transmission frames left.  They are the cast brass frames and
will soon be limited supply.  To duplicate these old parts has gotten
expensive and hard to source.  Three of the foundries that cast them
have now closed.
