All such manuals should be copied as a matter of course.  There's a
great wealth of information available, but originals are rare and so
easily lost or damaged.  Spreading copies around should save the
information, even if the original is destroyed.

I've been going through a box of papers borrowed from a long term
collector here in London, and there's an Artrio catalogue (perhaps
from 1923), a supplement for 1924, and monthly supplements for 1925.
There's also an original Artrio serviceman's sheet which would have
been filled in the field to describe the instrument's condition, and
which has a list of actions for the serviceman on the reverse.  Copies
of all these will be available as I have time to make them, and would
go well with an owner's manual.

I can confirm that Rob DeLand really _is_ a rabid collector of
paperwork.  It took many hours to go through his filing cabinets of
copies selecting the ones I really coveted!  He started me off over
here looking for things to copy.  The 1300 page 1914 Aeolian catalogue
is my best achievement to date.
