Did you ever receive a response? I have a Honeymoon treadle machine and have sewed on it, so I can at least tell you how mine threads. I am a new member and will see if I can send you a photo using this website. I just tried. I do not know how to do it. I need a manual, though, so was wondering if you ever found one. I found one for a model that is similar to mine, but not the same one.
