I just wanted to repost Miriam's helpful link, as I've been having trouble finding a manual for the machine that's free! I can't purchase a manual from sewusa.com or tias.com since I don't know what machine might be its equivalent... it took me a lot of searching to find Miriam's generic manual link back on post #80. Since this thread is up to 31 pages, I hope you won't mind if I repost for someone who might come along later seeking the same info! Now to find out if this will help me with my apparently left-homing machine...
