It's one of those things that bothers me: People sell downloads of sewing machine manuals, yet they don't own the copyright. You might think it's still good value and convenient for you to have a printable copy but it annoys the hell out of me. If you didn't write it, you shouldn't be making money from it.
Here are two sewing machine manuals I Googled and found really difficult to locate. These are both scanned manuals that I scanned myself.
Please don't attempt to sell it. Click the link, the pictures are just pictures.
