I am looking for any help with my search for needles and a manual for a Singer 5-9, The photo does not do the scale justice, It weights at least 500lbs. It is 4 feet wide. It is much larger than the class 7 but has a similar bobbin, but i don't own a class 7 so I am not sure how close the bobbin holder is. I guess I am looking for someone who has a class 5 machine or any direction to point me. Which industrial sewing store might know about this machine? Thank you for letting me post my question here.
i found this old book in the Smithsonian on-line archive but this doesn't help me enough to find an equivalent needle.
