Hi all....I picked up one of the 291's, checked out the different plays in the machine and the guy said it was ready to run on 3 phase which was OK with me. But when I got it into my garage and started cleaning it I found there was no bobbin holder or as some manuals refer to a bobbin cap for it. I contacted Simard in Cambridge and they told me I had to replace the complete hook assembly for around $650.00. Wow, looks like I may have bought a good door stop. I have been on the internet and checked out different sites and have a variety of part numbers and pictures of bobbin case/caps that could work with this machine. Not knowing what I need is frustrating. My question to anyone with a 291is, what part do I really need and where can I get it even a picture would help. Any directions would be a great help. thanks in advance Bob
