Hi! I'm new to the board too. I don't know your friend but noticed your interest in vintage machines. Maybe you could help me? I just got an old dial n sew and it does not have a manual. I googled the model and came up empty. It is not stitching well. I think it may be the tension as the chain where the 2 threads come together is not right. I tried what I think is the tension knob in all the settings with no luck. I don't know where to oil it either and how often. Any idea about a manual? Thanks
