Who Made The Ydk Sewing Machine And Can I Find A Manual For One?

YDK Motor was used on many machines .. But I have a PW-201 machine. Heavy built. Med. Green in color. Gear driven.. It was made by Thompson. Look on E-bay for that brand.. I have found a manual for it.

I just bought a used YDK sewing machine. It is a Delta Deluxe machine model YDK on the motor. I suspect this one at least 40 years old, it is all metal, not plastic, very heavy. They don't wear out.

Some where on the machine there has to be a manufactureing tag. Look underneath look in slideing pannels.fin out who the manufacturer is, kenmore, singer etc, on this tag will be serial numbers and maybe Even a address or 1800 number.
