copy of the Singer manual!

Description:
This listing is for a professional reproduction of the Singer Manufacturing Co. Service Manual for classes 337 and 338 sewing machines. This is NOT a standard "Xerox" copy of the Singer manual! It is professionally printed on the same heavy-weight brilliant-white chrome 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 50 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 50 years.
In fact, if we didn't tell you,
you could not tell the difference
between this manual and the
original manual!
This 44-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:
