Younkers is a regional dept store in the upper plains/midwest. We have had one as long as I can remember. Nice looking machine but have never seen one before. Since it is made in Japan it is probably a well made machine. Their quality in the 60's and 70's was superb. It might be hard to find a manual, but attachments should be fairly easy depending on the shank. Looks like a slant shank??? Take your needle to the store and see if it is a long needle or a short. Also take the bobbin to determine bobbin size. If there is a repair place close by they may be able to help you.
