I would like to trade an unrestored Ampico B stack for another
Ampico B stack hat is wider.

This best way to measure the B stack is from outside edge to
outside edge (not including the mounting flange) of metal plates at
each end.  The stack that I seek should be 49-1/4 inches and would
most likely come from a Knabe or Mason & Hamlin.  It must have the
expression unit built into the stack and be complete.

The stack that I have for trade will fit a 5' 4" Chickering and is
47-3/4 inches wide.  This is a complete stack, with rounded cover
and it has the subdue port on the expression units.  It is in very
good unrestored condition.
