Hi,I am new to this so bear with me. I have acquired a Singer treadle machine. The only No. I have found on it is G7789982. I would like to learn more about it so if you could give me information of how to get a manuel for it I would appreciate it. It sews well but would like to get some parts for it. Other than a manuel it also needs the thread holder for the top. Any help would be greatly appreciated. thanks jan
