Thanks so much for your reply...
I was looking on the web today and came across somethings about this machine...way too cool.
I am thinking that this has an Oscalating (sp?) hook vs. the rotary hook.
I do not know the difference, yet, and perhaps will pm you with some questions and photos...
I think this would be a wonderful thing for me to tinker and perhaps try and fix myself since it doesn't seem to be anything major...yet
