Is there somewhere to get the book or somewhere I can learn more about the Canu numbers. I'm a bit crazy when it comes to machine part sizing indexes. Unfortunately, I have that special kind of OCD that makes me unable to relax or sleep until I find out the reasoning or logic behind something like "sewing needle systems." I've got a job fixing sewing machines and today I needed to find a replacement for a needle that was smashed to bits. I took 2 hours of digging to make sure I didn't order a TVx1, DCx1, or DCx27 and get the wrong size. i finally pulled a parts schematic that luckily had it listed, but I hear there's a difference between these as they have different Canu but I don't see a place to buy or look through "Guide to Sewing Techniques." do you have an author or ISBN? I would love to know more. It seems everyone figures out what they need and get back to work while I'm still twiddling my thumbs and trying to figure out what these notations could possibly be in reference to. Thanks for the knowledge
