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.

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.

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.
