Hello All,  I have just finished rebuilding (what I thought was) the
last component on my 1925 Marshall and Wendell upright Ampico stack.
During the re-tubing process I discovered that the stack is missing
the three pieces that sit on top of(?) the automatic expression cut-out
Block.  These are labeled as Figures C, H and I in Illustration 7 of
the 1923 Inspector's Reference Book (page 14).

Does anyone have these available for sale or trade?  Please send an
email to <rbbst3@pitt.edu> if so.

Many Thanks,
Rob Buckingham
