Description:
This
listing is for a professional reproduction of the Singer
Manufacturing Co. Service Manual for class 401 sewing machines. This
is NOT a standard “Xerox” copy of the Singer manual! It is
professionally printed
on the same
heavy-weight pure-white paper
as the original Singer manual! It is super clean, the
text and the illustrations are very sharp, and it is nearly identical
in size and in paper type to the original Singer manual. This manual
is not a bunch of pages stapled at the top corner. This manual is
professionally bound
, just like the original Singer manual.

***************
This
manual is professionally bound,
just
like the original Singer manual.
***************
Unlike
the original 60 year old manual that has become frail, brittle,
mildewed, stained and yellowed after so many years, this manual looks
like an original Singer manual that has been preserved in
NEW
CONDITION
!
Just
like the Singer company printed their manual on their in-house
printing press, we printed this manual on our in-house printing
press. This manual may also serve you for the next 60 years.
In
fact, if we didn’t tell you,
you
could not tell the difference
between
this manual and the
original
manual!
This
42-page full-size Service Manual is complete and very clean with no
“black dots,” smudges, stains, or any other imperfections.
No pages are missing, dirty, or damaged.
The
manual includes descriptions and illustrations which will show you
how to do the following

NOTE
eBay
5-Star Rating System
:
Due
to eBay’s new Star rating system and it’s lack of explanation and
clarity, I would like to try to give you an insight as to how it
affects our business. You would think that a 4 star rating would be
good as eBay says. Not So! Anything less than a 5 star rating on all
categories might as well be a Negative feedback score. If you are not
completely satisfied with any transaction and believe it to be our
fault, your fault or nobodies fault, contact us and we will take care
of the problem.

1.
We inventory and have in stock every item that we list for sale.
