Thanks for the advice and information about manuals. I am sure I will find one now. I plan to take the Elna to a shop that knows all about Swiss machines and have it cleaned and checked out. I am happy to know that it will stitch backwards. I hate tying threads because my fingers anymore wont do what I want them to. Looking at pictures of Elna machines on the Internet, I think this one was made around 1952. It is mostly a whiteish color with a light blue top on the machine. I am really looking forward to learning more about this machine. I don't do a lot of fancy sewing, but this may lead me to do some things that are different. It came with a box full of attachments.
This woman's death was a real tragedy. She pulled out onto a US highway in front of a fully loaded semi going 65 mph. She was such a wonderful, caring person. Keep her in your prayers. They are still cleaning out the house and if they find any bias tape I will certainly let you know, J Miller.
Thanks everyone!
