Welcome to the QuiltingBoard! That is a clone of a Singer model 15. If you search this board for "15 clone" you will find some general information. These machines were manufactured in Japan after WWII, the US having provided the engineering information for the Singer model 15, to help rebuild the Japanese economy. They were manufactured by the millions and have just about every name across the arm you can imagine (within reason). "Fair" could have been a regional store somewhere that wanted a machine to sell with its name on it, or...it could have just been a word someone decided to put on a machine.
