I hate to admit this, but I haven't used it in a long long time. Lately, I've been wanting to, but not sure where I would move it to be able to use it. Right now it is in the room with my uncle. It does stitch a beautiful straight stitch. Now that I seem to be doing more quilting than garment sewing, I think I would love using it.
Congratulations on your lucky purchase! You were indeed fortunate to get so much with it too. I don't recall ever having a manual for mine. Not much else came with it that I recall either. It is sad when people only want the cabinet and not the machine. How little they realize that these machines are worth their weight in gold.
Golly, I learned something, didn't know you could lower the feed dogs on it!
