I got a Younkers brand sewing machine yesterday and need info .I doesn't have any feet except one for a zipper. I wonder if anyone has heard of this before? The lady said it was from a store in Iowa. Like Sears but smaller. The name of the store is the same as the machine.
on the back plate it says manufactered by Koyo machines in Osaka,Japan. Its called the centennial series . St Louis , Mo. there is no manual or any other info on it. I'd love any help . Also, all metal including the case(around the parts). It is in a wooden cabinet.

Please show us a picture of the machine. Hopefully
there is someone out there that can help you.

yes, a pic would help a lot

Ok my mind is gone !! hehehe Here are the photos. This machine sews like a charm. BUT I have only one needle that fits and it must've come with the machine in the 70's.

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.

This is just one of many badged, Japanese clones. I have one similar to it. Good machines and they are tanks.

I love mine too. What does badged mean?? Its a new term to me.

It means the manufacturer didn't put their own name on the machine, but the name of the store where it would be sold, or sometimes some other generic name. Like Kenmore is on Sears sewing machines, but many different manufacturers made them over the years, including Janome.

wow. Thanks for the info. I hadn't heard that before.

Manual??
 

Do you happen to have a copy of the manual for this machine? I just bought it’s twin and have only been able to find a user developed manual that just shows the basics of threading needle.
