You have the original workhorse serger for the home sewer. I have the same one, bought it new in '81-82. I don't use it much now, since I'm doing more quilting than sewing, but it's been well worth the money I spent. In all the time I've had it, it's been serviced twice, and it has been used, believe me. I have a manual for it, I'll see if I can find it and make a copy for you, as far as the needles, I would go to a sewing machine dealer and get them there. If you have any other questions, please feel free to PM me and I'll try to answer any questions.
